Thanks for all the replies. I really wanted to fit TSMM, Soarin, and RR in the same day (even the same morning if possible). We have a two year old, and TSMM was always a HUGE hit with my other 2 girls at that age, and one of the few where little and bigger kids liked it equally as the "baby". My oldest is DYING for Soarin and will need to get on it the first day. It's her favorite, and our last trip to WDW was a Make a Wish trip for my middle daughter. You only get a 3 day pass to WDW on Make a Wish trips, (the rest of the time you get Sea World, Universal, etc) and of those 3 days we just didn't make it to Epcot. She was really bummed. And of course, we're excited to try RSR. We have 5 day passes so I know we'll get to all 3 eventually, but it would be great to fit them all in that first day.
We have 5:30 supper reservations at Carnation Cafe that day in DL, but could maybe return back to DCA for a late RSR return time I suppose. As a WDW person still wrapping my head around that one.
