If you have a friend who is not afraid of flying, the best gift for him/her is a round-trip plane ticket. Ryanair has great deals often, if you book in advance, he/she will surely love it!
So number 1 on my list – plane tickets!
The Scratch map I got last year was (and still is) one of the greatest gifts I ever got!
As dull as it may sound, another good idea is a wallet. It has to be just the right size and be big enough to fit your money, credit cards, coins and whatever, and of course easy to use. Unfortunately I haven’t found the perfect one for me yet.
Backpack! We have at least 4 at home and sometimes they’re not enough! Now I got my eyes on a bag like this. You can find more models here.
You could also look for useful stuff like: travel sheets (cocoons) and towels, travel kits with shampoo and shower gel and so on.
Gadgets – external batteries, solid chargers, headphones, cameras, etc. Or a digital scale for your luggage.
Personalized travel journals! (there are an infinite numbers of models out there). Keep in mind that it”s for a fellow traveler, so find one with light covers. This one I found here.
I am waiting for your gift ideas and lists olso! Cheers!
