Cash or Card in Mexico: What Works Best for UK Travellers?

You land in Mexico, grab your bags, and within about 10 minutes you’re already making your first decision:
👉 Cash or card?
It sounds simple… until it isn’t.
Because one minute you’re tapping away like you’re in Amsterdam (where I’m convinced physical money doesn’t exist anymore), and the next you’re being told “cash only” with a queue building behind you… and no idea where the nearest ATM is.
We’ve done this a few times now — and trust us, Mexico sits right in the middle.
Not fully cashless.
Not cash-only either.
Get it wrong, and it’s annoying.
Get it right, and you don’t think about it again all holiday.
Here’s what actually works.
💳 Using Your Card in Mexico Is Generally Easy
Resorts, hotels, restaurants, bars, excursions — all absolutely fine.
You’ll want to use your card for the majority of things and save cash for when you actually need it.
We’ve used card for:
- Hotel fees & taxes
- Excursions and add-ons
- Private transfers
- Shops in tourist areas
- Duty Free
No issues… as long as you’re using a normal debit or credit card.
Travel cards can be a bit hit and miss.
We’ve had a few moments where terminals just flat-out refused them — especially at resorts — throwing up errors like they’ve never seen one before.
⚠️ One Thing To Be Ready For On Arrival
One of the first things you’ll usually do at check-in is pay the environmental tax.
It’s not a huge amount… but it always comes at the worst time.
- Your card isn’t working — or the resort doesn’t accept travel cards
- You’ve got no backup (or one that’ll sting you with fees)
- You’ve got no cash
After a long flight, the last thing you want is standing there trying to figure out how to pay it — or where the nearest cash machine is.
You end up using the first one you see in the lobby…
Uh oh.
Big fee incoming.
Don’t worry — we’ve got you.
We cover the cards we actually use later in this post, so you can sort it before you go and enjoy your holiday without getting stung… or your card throwing a tantrum.

💵 Bring Enough Cash For Your First Day or Two
We recommend bringing enough pesos to cover your first day or two.
It just takes the pressure off straight away.
You land, get checked in, grab your first drink… and you’re not immediately thinking:
“Where’s the nearest ATM?”
You can start tipping straight away (which, trust us, helps 👀), and you’ve got enough for a quick shop run for snacks, smokes, or anything you forgot.
Just try not to forget the essentials in the first place — resort shops will happily charge a small fortune for things like suncream and basics.
We’ve covered what to bring (and what to avoid buying out there) here 👉 Mexico Resort Essentials Guide
💸 How Much?
For us, around £150–£200 worth of pesos has always done the job.
It’s enough to get you going without carrying loads of cash around or relying on the room safe for your entire holiday budget.
That’s a big no-no.
💱 Don’t Overthink the Exchange Rate (Yet)
For this amount, it really doesn’t matter that much.
You’re talking small differences — not worth stressing over before your trip.
👉 Convenience wins here.
🏪 Where To Get It
Anywhere decent will do the job:
- Tesco (Clubcard rates are usually solid)
- Asda (normally competitive)
- Post Office
Order it in advance, pick it up, done.
Don’t leave it until the last minute either.
⚠️ Where Card Suddenly Stops Working
This is where people get caught out.
Because Mexico can feel modern… until it suddenly isn’t.
You’ll be tapping away all week thinking “this is easy”…
Then out of nowhere:
- No card machine
- “Machine not working”
- Cash only
And now you’re stood there digging through your bag like you’ve never seen money before.
You’ll need cash for:
- Taxis (especially random ones)
- Tips (big one)
- Small shops / local places
- Market stalls
- Street food
- The occasional “system down” moment
And trust us…
“Card machine not working” is basically part of the culture.
Sometimes it’s genuine.
Sometimes… convenient.
Either way, you’re paying cash.
💵 Use Cash For Smaller Shops & Snacks
We also tend to use cash in smaller shops or anywhere that feels a bit… “guessy.”
Not saying it happens everywhere — but we’ve definitely had a few moments where the numbers didn’t quite add up, and we had to question it before getting the correct price.
Whether it’s the exchange rate, the terminal, or just a “mistake”…
It’s one of those things you don’t always spot until later.
👀 Why It Can Catch You Out
Prices are often shown in pesos, and when you’re converting them in your head on the spot, it’s easy to miss something.
Especially when you’re tired, sweaty, and squinting at a tiny terminal in the sun that’s perfectly angled for maximum annoyance.
And sometimes… yeah, it just doesn’t feel quite right.
If you’re from the UK, make sure you always pay (or at least ask for the price) in pesos.
Sometimes the cashier will quote you in USD instead — and that’s usually where it starts going wrong.
You’ll often get a rough exchange rate from them…
And then your bank may do its own conversion on top.
👉 Double whammy.
And in the moment, it’s not always obvious.
The difference between something like $1,500 and $7,500 on the perfectly aligned terminal might not exactly jump out when you’re still partially blind from the sun and melting.
But you’ll definitely notice it later when you check your banking.
By that point?
You’re back at the hotel trying to remember what you even bought…
heading back for an awkward conversation that goes nowhere…
And good luck proving anything after the fact. You may get away with a chargeback depending on the amount.
Receipts? Half the time they’ve “run out of paper” or the machine’s “not working.”
Funny that.
Don’t let this put you off. Most people are sound.
But there are definitely a few chancers about who’ll take that little bit extra if they get the chance.
Nothing wild… just enough to catch you out if you’re not paying attention.
💸 Why We Stick To Cash or Use Virtual Cards
For these kinds of places (which are pretty few and far between):
Cash just keeps it simple.
What you see is what you pay.
No maths.
No second-guessing.
No checking your banking app wondering what just happened.
If we do use card in these situations, we keep it controlled.
Usually a separate pot, a virtual card or travel card with limited funds on it.
That way, even if something looks a bit off later, it’s contained and easy to deal with.
No damage, no stress.
💳 The Cards We Actually Use (And Why)
Even though cash plays a big part in Mexico…
You’re still going to be using your card a lot — including withdrawing pesos while you’re out there.
So it’s worth getting this bit right.
Because not all cards are built for travel.
💸 Why Your Normal Bank Card Can Let You Down
A lot of standard UK bank cards will quietly charge you for using them abroad.
We’re talking:
- Foreign transaction fees
- Poor exchange rates
- Random little charges that add up over the week
You won’t notice it on one payment…
…but after a full holiday, it adds up.
💳 What We Actually Use
We keep it simple.
- Monzo Debit Card
- Virgin Money Debit Card
- Credit Card (for hotel deposits and random stuff)
- Asda Travel Money Card (the OG Backup)
That’s it.
✅ Why These Work So Well
- Little to no foreign transaction fees (Mastercard rate)
- Fee-free withdrawals up to a point
- Easy to track spending in real time
- Can split money into pots (perfect for trips)
- Virtual cards for extra security
And most importantly…
You’re not getting quietly rinsed every time you tap your card.

Prep Your Cash Before You Actually Need It
Not all ATMs are equal in Mexico.
Especially at resorts.
Some are decent.
Some will absolutely rinse you.
And some… just don’t work at all.
And the worst part?
You’re often a bit stuck.
Resorts can feel isolated, so when you need cash, you’re usually working with whatever’s nearby — not always ideal.
📍 A Little Bit of Planning Goes a Long Way
This is where a bit of prep pays off.
Before you go, it’s well worth joining a couple of Facebook groups for your hotel.
Sounds a bit over the top… but honestly, they’re gold.
People will tell you:
- Which ATMs to use
- Which ones to avoid
- What fees to expect
Just make sure you mention where you’re from — it can actually affect what people recommend.
Like Christmas dinner… it’s all in the prep.
Do the boring stuff now, and you won’t get the hiccups when it actually matters — Your holiday.
🏨 Real Examples (From Experience)
At Bahia Sian Ka’an, the best ATM is over at the Hacienda.
At El Dorado Seaside Suites, you’ll want the one near the tennis courts by the staff area.
Random? Yes.
Useful? Also yes.
💸 How Much to Withdraw?
We usually take out enough to last 3–4 days at a time.
Because ATM trips can be a bit of a mission — especially in the heat.
But at the same time…
You don’t want all your holiday money sitting in one place either.
Lose your wallet, drop some cash, or have a dodgy moment…
Game over.
⚠️ Don’t Leave It Too Late
The better ATMs — the ones with lower fees or decent rates — do run out of cash.
It happens more than you’d think.
So don’t leave it until you’re completely out.
Because nothing kills the vibe quicker than being skint in 30-degree heat, queueing at a broken machine.
💱 Quick Peso → Pound Trick (Rough but Works)
We’re not doing maths on holiday.
So here’s the easiest way to keep a rough idea of what you’re spending:
👉 Divide pesos by 20
That’s it.
🧠 Examples:
- 200 pesos ≈ £10
- 500 pesos ≈ £25
- 1,000 pesos ≈ £50
- 2,000 pesos ≈ £100
💡 Even Easier
If you can’t be bothered with that, just remember:
👉 1,000 pesos ≈ £50
Then scale up or down from there.
Why this works:
The rate usually floats somewhere around 20–24 pesos to £1, so dividing by 20 gives you a quick, slightly generous estimate.
Better to overestimate than get caught short.
🍹 Final Thoughts
Mexico isn’t card-only, and it’s not cash-only either.
It’s a bit of both.
Use your card for the easy stuff.
Use cash for tips, smaller places, and anywhere that feels a bit “off.”
Have a backup.
Bring some cash for day one.
Don’t overthink it.
Sort that before you go, and you won’t be worrying about money when you’re out there.
Just sun, food, and a few strong margaritas 🍹
