I just happened to see this in an article on CNN.com about the 10 most popular travel scams and I thought I'd better share it:

Orlando

Here's a scam so bad even Mickey Mouse took a stand. Guests in hotels around Disney World have been finding pizza delivery menus conveniently slipped under their doors, but place an order -- and make the mistake of giving your credit card number -- and you'll really pay. The phone number isn't connected to a pizza parlor but to identity thieves. Disney World supported a law designed to crack down on the people handing out the fliers, but Orlando police say the problem persists.

Solution: If you're craving a slice, get a recommendation from the hotel.
