My DD, 9, bought me one of the
Disney Cruise waterproof plastic things from the gift shop. She also bought one for herself. She got the smaller of the 2 sizes. They were fabulous! I loved having it in the World after we left the ship too.
I was able to put a credit card in it, my KTTK card, my ID, and a couple of bucks in it. It was easily accesible. At work, my ID is on a lanyard - so I am used to wearing something like that around my neck. I loved having my most important things so accessible!
With my DD having one - it gave me the confidence that she would not loose her KTTK card also.
The only thing I did not like about these lanyards was the "breakaway feature." While the actual lanyard has a snug fit at the connectors, I think it is a safety feature that they must be able to break away if they are yanked (at least it is in the hospital where I work) - we just tied a knot near the end so it could not accidentally break away and fall off.
I think the smaller sized ones are about $5 or $6 in the gift shop. I am glad DD bought the smalller size - I don't know if I would have liked the "bulky" larger ones.
Have a great trip!
