Hmmmm, not certain how the laws are regarding that in England.

I'm not certain that any US park would want to accept the liability for caring for PDA/Smart Phone's.

Can you imagine if one was lost? If an employee went through pics? Obtained phone numbers? Made calls?

I like the idea, but can see it going over well in the States.

Mmm, fascism much? I think it's great that they're trying to get the parents to try to disconnect with the office and connect with their children but I would be darned if I were to be made to leave my iPhone. I think in the end it's a personal choice that should strongly be encouraged but not enforced. That's just going a little too far.
