If you'll have a car, there is a Walgreen that is maybe a mile from Hotel Plaza Blvd on SR-535 (from Downtown Disney, head up Hotel Plaza Blvd and make a right onto SR-535. The Walgreen will be on your right - I think at the first traffic light after you pass the turn for the Mary Queen of the Universe Shrine) that does one hour processing at about 1/2 the price of WDW processing. There is a Bennigan's right next door so you could drop off the film, get some lunch or dinner and then pick up your photos.
