I’d still get the book (and maybe a few travel magazines). Although I book everything online I still love looking through the physical copies for ideas and to help me get started. The ‘NYT 36hrs in Europe’ book would be a lovely gift for this because it gives a brief overview of the highlights of lots of different cities www.amazon.co.uk/NYT-36-Hours-Europe-3rd/dp/3836573385/ref=mp_s_a_1_4?crid=1ZYL985FXV5KK&keywords=72+hours+book&sprefix=72+hours+%2Caps%2C206&tag=mumsnetforu03-21&qid=1639846157&sr=8-4
I’d also really recommend this backpack as a ‘day bag’ (although I’ve used it to travel for 10days when I pack really light): www.johnlewis.com/sandqvist-roald-ground-organic-cotton-backpack/bronze/p5297631. I cannot recommend it highly enough and both my husband and best friend have bought one after borrowing mine.
A small travel wallet. Maybe with some Euros in to get her started.
A water bottle that collapses or clips to the outside of a backpack.
Luxury mini travel toiletries (Aesop and Cowshed have a lovely travel sets if you don’t mind spending a bit, otherwise Boots and ASOS have good options)
A power bank (make sure you get one that connects to her devices)
A multi country plug adapter (not hugely exciting but they’re really useful and expensive to buy at the airport)
Mini travel first aid kit. I’d buy a nice pouch from somewhere like Accessorize or H&M and then fill it with things that are actually useful (plasters, painkillers, antihistamines, immodium, blister plasters, mini scissors, mini bottle of aftersun etc).
Packing cubes are great. Especially if you can find the ones that compress bulky items like jumpers and jeans (the ‘Antler’ ones are excellent quality and last forever).
Sleeping mask, earplugs, a travel pillow, waterproof flip flops and a microfibre towel (especially if she’s staying in hostels).
A large, thin, cotton/linen scarf that can be used as a blanket/towel/cover-up. I bought a big cotton scarf in Tesco about 15 years ago for £5 and it’s probably my most used travel item.
