jewelery would you take on a 3 hour tour? And would you take a suitcase full of money?

Why would anyone take a 3 hour tour just to look at nothing but the ocean? I'll bet that small boat didn't have anything to do on it, either. But maybe they were on a 3 hour tour to a small island where there was a lot to do and planned to stay for a 2 weeks or something. Even that doesn't make much sense-why would a famous movie star, not to mention the others do that-wouldn't Ginger be worried that she'd be mobbed by the others (unless she was in disguise). Anyway, if I were going on a "3 hour tour", I'd probably just bring my wallet and sunglasses.

This is something that everyone knows - there is no answer. The show has huge holes, but you just have to overlook them because there are simply no answers.
