You can pick up speed passes at many of the rides. They tell you to come back at a certain time, and then you get to go on the ride at that time. Lets you play all over the park, until ride time. If you miss your time, I think they get you on the next go round. We never missed.
Also, there are "Vip" passes you can purchase about $100+ each person I think, or more, and they will take you through the tunnels, on carts and such, and you get to go on the ride when you get to them. No one knows you haven't been standing in line for an hour or more either. Seems like a very good deal, especially if going during the busy season, if you can spare the dough.
Good luck and have fun! Do your research ahead of time online(disney.com I think) and you'll enjoy it much more. Send for the maps they give out, and plan your route. Noontimes or during high heat should be spent napping or swimming at your hotel pool, and then shuttle back to the park in the early afternoon. If you arrive at the opening, shuttle to hotel at noon, swim, etc, go back around 4 and stay until the fireworks at around 10ish or later. Last busses leave a half hour or so after the park closes.
ps, make a plan on where to go if anyone in your party gets lost. My daughter lost us. They take them to the main street (courthouse?) building and keep an eye on them. I had frantic minutes of running and asking, only to have them smile and say, let me take you to your daughter...
