asmit - you could eat breakfast, lunch, and dinner at CRT in one day and still only use 3 meal credits. All meals, whether room service, TS, CS, dinner show, or signature dining all cost 1 credit. On platinum even Victoria and Alberts is 1 credit.
If you go to the disney site under reservations there should be a link for 2007 and 2008 packages - just keep clicking the links for plat or premium and there will be a pdf with a description of what is included. Under the recreation section for 07 platinum (basically the same for 08 and premium) it includes Golf (shoes, clubs, fees, golf cart, lessons), guided fishing excursions, water sports (parasailing, water skiing/wakeboarding, personal watercraft/jet ski), watercraft rentals (sea raycers, boston whaler montauks, pontoon boats, canoies, kayak, pedal boats), bike rentals, cane pole fishing, horseback riding, carriage rides, wagon rides, and mini golf. There is no limit to how many times you do these activiites. We have jet ski reservations for 3 times and parasailing scheduled twice. Several tours are also included however there are a few differences b/w plat and premium,
