We were also there on Monday and it was probably the highlight of our trip! We entered the park around 7 and headed straight to Tomorrowland. We rode the People Mover and Buzz before 8. Once 8 struck, we hit up the Speedway, the Teacups, Pooh, Peter Pan, and Small World in just over an hour. We slowed down a bit but still hit Thunder Mountain, Pirates, Dumbo 2x, Space Mountain, a photo op in front of the castle, and the Tangled photo op in the remaining time. Our only mistake was believing the wait time and not getting on 7DMT. They told us it would be about 15 minutes at around 10:35 so we chose to do Space instead. We made our last snack stop at 10:50 and headed out. Rather than wait for a bus, we walked to the Contemporary and got a Lyft from there back to All-Star sports.
Overall, we got 3 Diet Cokes, 2 Waters, and a Sprite, as well as 2 popcorns and a Mickey Bar.
Is 7 the earliest they would let you in? Or is that just when you happened to get there?
