Got to MK right at 4, & it rained (quite a common occurance last week) so we browsed some shops, spent $$ at the one in Toontown, got our girls in line for the Princess Meet & Greet, only needed Snow Whites auto, but it was a must, my 4 yr old loves her! After that we got out & did Philharmagic/TeaCups before they were shooing us out & over to Tomorrowland, side note **If you plan to eat before MNSSHP, get there before 6) we went into Cosmic Rays because it was pouring again, but they closed down from 6-7, just like the rest of MK, not sure if anywhere in Tomorrowland is open for snacks/food, but then we had to sit & wait till 7 to eat, which wasted some precious Party time (IMO) however, the Cosmic Dance Party with Stich started at 7 or 7:30 & my kids LOVED IT!! So it worked out for us! I think you should try to get to Cosmic Rays/Pecos Bills wherever if eating CS & order by 5:45, so you get your food, have time to relax, rest up for a great night at MNSSHP!
