We watched the Main Street Electrical Parade from near its starting point, near at Town Hall. When the end of the parade passed us, we raced to Adventureland. We were able to go on the Jungle Cruise and Aladdin’s Magic Carpets without waiting in line at all, because most of the people in the park were still watching the parade. Although we didn’t try it, you could probably apply the same principle and watch the earlier parade near Frontierland and run to find rides in that area as soon as the parade finishes.
