You can't get fastpasses for all the rides at one time. You can only get another fastpass when the time on the slip says you can, which is normally two hours. I've found it to be the best to check the return time of the fast pass. I actually was going to get a fastpass for BTMR and noticed that the return time was about 25 minutes after getting the fastpass (i didn't get it because we left early due to me being so sick). If we didn't have a five year old with us, we were going to get a fastpass for Buzz, come back in about an hour when our time came up. We were going to wait in line for space mountain for an hour while we waited for our return time for Buzz. Now it sounds like we should have gotten a fastpass for space mountain, but the return time for SM was about three hours later. So, I take an hour hit waiting for SM, ride it, then run onto Buzz, which takes care of the big rides in TomorrowLand. The timing of fastpasses is what makes them work even better then just getting to the front of the line first. Also, make sure that you ride rides that don't have long waiting lines AFTER you get a fast pass. Such as, in FrontierLand, get a FP for either Splash or Thunder MTN., go onto Tom Sawyer's Island and hit the Haunted Mansion. Go back, and ride either mountain. Get a FP for the other mtn in frontierland that you didn't ride before. Ride POTC, check out Swiss Family Robinson treehouse, see the Birds of the Tiki Room, and go back to the mountain for the fastpass. The same thing with FantasyLand, get a FP for one ride, hit the others, check out Philarmagic, IASW, and toontown. Normally Winnie the Pooh is the longest line in FantasyLand with Peter Pan coming in a close second.
