With MaxPass, you can get a new FP every 90 minutes. So, say you're in the parks in the morning and notice that RSR is going quickly. At 10am, you grab a FP for RSR at 5pm. At 11:30, you could then grab another FP for a different ride, say Soarin' at 4pm. At 1pm, you grab a FP for Incredicoaster at 3pm. Then at 2:30 you could grab a FP for something else, then go ride Incredicoaster, Soarin' and RSR all with FPs. Just an example, and it depends on how quickly the FPs are going for each ride that day!
