If you do it right, you can collect multiple FPs of those rides in the morning and cash them in the rest of the day. However, if you want to ride Peter Pan or other Fantasyland rides, I would suggest that those be your first stops of the day (assuming you will be there early).
Try to beat the crowds to Peter Pan, Dumbo, and Mr. Toad (if you want to ride them). Then send a runner, or walk yourself to Space Mountain. They should be giving out FPs for a half hour to forty-five minutes later. Ride the Carousel, Pinocchio, Snow White, and Alice. Then send a runner to get Indy FP. Again, it should be a return time of forty-five minutes to maybe an hour. Now you can ride the Haunted Mansion, Pirates, Jungle Cruise, etc. As soon as your window opens up to obtain another FP, get the Big Thunder one. Now, it should only be 11am or so. You are holding three FPs. Decide which ones you want to start doubling up on.
If you don't care to ride the Fantasyland rides, you can instead obtain a Space Mountain FP at 8am, and then move to Indy, and then Big Thunder. You could probably obtain all three FPs by 10am or so, riding Buzz, Jungle Cruise, Pirates and Haunted Mansion in between while waiting for the window to open. It really depends on what you would like to ride and how much you are willing to criss cross the park during the first few hours. However, doing this early will save you so much time later on! So I highly recommend.
