Advice for teen traveller please!

[NoWeaponsOnTheTable]

My teen is off on her first solo (sans parents) holiday very soon. She is going to Spain with a group of friends, all lovely sensible young people.

I am not a seasoned traveller and haven't been abroad for over 10 years so feel a bit out of the loop and not sure how to advise! Has anyone got any top tips for her? All info gratefully received!

Make sure she has decent travel insurance. Teens don't always think of it.

Take photos of her passport and any important documents.

Ensure that she has your contact details written down in case she loses her phone or it gets nicked.

Get Revolut or similar for payments.

Tell her to stay with at least one friend at all times. And guard drinks when out etc.

How old is she and where will she be staying/how are they travelling?

Don't worry, she'll be fine.

The above plus sunscreen, and keeping her debit card separate from her phone, is cracking advice

Worry not, it sounds fun but tame

Check her mobile phone will work in Spain; teens are useless without them.

Thank-you all!
On it with Revolut and will sort phone, insurance is sorted.
They have a lovely air bnb. All travelling together and have a plan to buddy up in pairs so even in the smallest chance they do get separated they will all be with a pal.
Good call to write down details.
I have copies of passport.
Just worried I have forgotten something obvious.

I used to advise mine that no matter what high jinks they got up to that they should under any circumstance go swimming after drinking.

Tell her measures of alcohol in cocktails are much much more generous in Spain so she may well get drunk a lot quicker than expected.

Set up a shared Dropbox folder for copies of flights, insurances, passport copies, GHIC, contact details and then get her to have the app on her phone. She then has all details easy available instead of digging through paperwork.

And you can email her/send a WhatsApp with copies as well if necessary.

Do any of them have any allergies my dd went away with friends last year and 2 of her friends had allergies which the group were all aware of and my dd had them written down

All great and sensible advice! Thanks all
