So that explains your away message
Damn, that sucks though. I know my dad lost the wallet one - he got it back (at the lost and found), just without the $60 he had in it. A crowded Disney World must have a lot of pick-pockets (where his was "stolen" or it fell out of his pocket).
As for you, you may have to hope someone returns it to you. Usually, I keep my wallet in my pocket (or in the glove apartment by the driver's seat.
I feel bad for you man - I don't know waht else you can really do. If you had credit cards or any information in the wallet, you may have to tell your parents quickly (as bad as that seems) so you don't get burned in the long run. I don't know what else you can do though, except pray someone finds you and gives it back.
