We had 3 different experiences in July. Once we were only allowed to line up early (still an advantage over the regular park crowd). Another day we rode twice before the park opened. We could have gone again, but we wanted to line up to be among the first on Peter Pan. And one of the days was truly magical. We rode several times in a row. More than once, the ride was mostly empty! We were one of the only families done with breakfast that early.
We were allowed to enter the park at 7:45 and go directly to BOG even with an 8:25 reservation one morning (another morning we had an 8:00 and the other we were at CRT). No one told us we had to wait until closer to our reservation time. We were the second family to arrive at BOG that morning.
