Last June at TT, MS, and Soarin we got paper tickets to be used in the FP line for each ride. The paper had the ride, the date, and baby swap on it. For the fastest time in doing your planned itinerary. I would suggest having 1 adult run over to Soarin' while the other 2 go to TT. HAve one of these adults get into line and get the baby pass. There is a great area to sit down between MS and TT. When the adult with FP arrives from getting FP with everyone ticket. The 2 adults left walk over to MS and 1 of them gets in line with a baby switch pass. This leaves one adult sitting on a bench between the 2 rides with the baby while the other adults are riding. When everyone comes out check your time. You want to head over to the Living Seas by 9:45 to make the first show of Turtle Talk. After the show use your Soarin' FP (which should be for something like 10:00-11:00 (most FP don't start until an hour after opening). If you had time earlier a set of people could have gone on TT or MS again, otherwise go right after lunch. Stop of Character Connections near Innoventions during the morning hours for great character interaction that is air conditioned and well organized (it is normally not very crowded and you get to see at least 5 characters). I think that is all you said you were worried about seeing. If you have a little time to spare you might enjoy immagination (which all of you can ride) and would be on your way out.
