To me, part of a successful park strategy is to have a separate fastpass strategy. Each time you get a fastpass it tells you when you can get another. We make sure we don't waste a single minute and always have at least one and sometimes two fastpasses in our pockets. Also, if there is a ride that only the kids want to do (R&R Coaster in our case) we still get four fastpasses and let the kids do it twice while we chill out at the food court or the shops. A good fastpass strategy is more vital the busier the parks get. But I do feel a certain satisfaction walking straight to the front of a 90 minute line with my fastpass in hand.
