Spain
The Alhambra is beautiful and really worth a visit. You can see parts of it without tickets but if you want to see the palaces and the wonderful gardens you need them.
Try and book online in advance as the queueing system for buying there is badly organised and can take hours.
This is the official site in English for buying tickets:

Thanks goodness we haven't needed to actually use them yet, but I bought two ID wrist bands for the kids to wear on holiday in Granada, in case they got lost in the city or at the Alhambra.
They're made of velcro so are easy to adjust to fit small wrists. You write your name and contact details on a waterproof piece of paper and slip it inside the little pocket on the inside of the wrist band.
I'm sure they would be good for the beach too.
