Back in the old days, before they took phone reservations, you had to line up day-of at the esplanade to get reserved Fantasmic! seating on the balcony of the old Disney Gallery. I got there at 3 a.m. and was first in line, but the line was 10 people long within a half hour. I remember some kindly security guards and custodians stopping to say hi.
Enjoy your early morning line-up!
