Most people take loads of photos in Florida but I think 20 x 27 (540 pics) might just be too many and think of the processing costs! You can purchase film and disposable cameras in Florida so if you do run out, it's easy to get some more.

Camcorders are, of course, allowed in WDW although you cannot use them in the lines to the rides or on the rides themselves. As you're likely to get wet on some of the rides, you'll need either a totally waterproof cover or some kind member of your party who'll look after your camcorder for you whilst you're on a ride.
