Get there at least an hour to an hour and half before the park opens. As soon as it opens to the public (hotel guests will be in there for EMH). As soon as the rope drops on Main Street, one of your party should go straight to one popular attraction (with everyones tickets to the park) to get FastPasses while the rest strolls to another popular attraction. Stroll leasurely and wait at the line que for the one who went to get the FP. Hold on to the FP's even if the hour has expired. They are good all day. As soon as the time comes up for that FP, you will be allowed to obtain another FP for a different attraction. Keep doing that throughout the day, as soon as possible. Send one person ahead while the rest stroll. (This is why I have teens). If the first set of FP's are good from 9 to 10, at 9, you get another set. Again, if you don't use the FP during the time, they can still be used. We do this and usually end up with at least three or four sets of FP's by noon. We also would obtain FP's, then get in line for the same attraction. This lets us enjoy the line que and then ride again later. Visit Fantasyland first, it gets crowded fast and stays crowded, with no FP attractions. Good luck, and with a little planning and strategy, you will be able to see everything.
