I did a 4 park day on Tuesday, August 15 with my teen daughter. It was SUPER fun! We had the benefit of using the express transportation (super bummer that it is ending), so that helped us out timewise. We really didn't have a set goal for the parks, except it was our only morning at HS and my daughter wanted to see the Beauty and the Beast show, so we worked around that.
Park #1 - MK - We started with 8:00 BOG breakfast. Even though it was EMM, we got on 7 dwarves a little early. Our ride photo was at 8:59. After that we rode Winnie the Pooh, People Mover, and Space Mountain standby. We left on the Express bus to Studios at 10:20
Park #2 - DS - We grabbed some popcorn and watched the 11:00 Beauty and the Beast show. We quickly made it to our fastpasses at RnRC, followed by ToT. Our timing worked our perfectly here, as I had booked our RnRC fastpass time to expire right after Beauty and the Beast ended, so that we could head right to ToT. At 12:10, we boarded the express bus to Animal Kingdom
Park #3 - AK - We were able to pick up a fastpass for Everest for 1:00, so after grabbing some falafel at Mr. Kamal's (so tasty), we rode Everest once, and then checked and another fastpass was immediately available, and then another! We also rode single rider twice. So, we rode Everest at 1:00, 1:12, 1:20, 1:28, and 1:42! It was SO fun. We grabbed a couple Dole Whips while we waited for the 2:20 express bus to Epcot.
Park #4 - Epcot - We picked up a fastpass for Soarin after our Everest rides, and rode that at 3:00. Had lunch at Sunshine Seasons, and had our picture taken at Spaceship Earth at 4:20 and headed back to our hotel and collapsed in our room by 5:00.
It was a great day!
