We met Merida yesterday and arrived at park open since she was our must-do that day (9am open, so we were in line around 8:55). We were first in line. By the time she opened the doors to meet people, there were maybe 7-8 families behind us in line. We didn't need to go first but wanted to make sure that we met her and got to continue on to Gaston later! No one else even showed up for a good five minutes after we did.
