I lived two miles from Disneyland for years. On the night of the last Main Street Electrical Parade we thought it would be fun to go over and watch it. I called a friend who worked at the park and we were comped in.
Unfortunately, a lot of other people had the same idea...and I mean A LOT! You don't want to be in Disneyland when it's at capacity which, at the time, was 50,000. It was so crowded that it took nearly a half hour to get from the entrance to the middle of Main Street. People were packed like sardines with rope barriers keeping people on the sidewalks and not in the streets.
It was so unpleasant that my wife and I turned and went home.
