So --- where is the best spot to see Spectomagic and how many minutes from the published start of the parade will it be at that location?
A couple of popular spots are in front of the Hall of Presidents,
and in Frontierland, on past the Country Bears area.
Start times (assume a prompt start at the top of the hour)-
HoP area, 18 minutes after starting time.
Just past the Country Bears entrance, 24 minutes after starting time.
The above times apply UNLESS:
the fish won't swim up hills,
the batteries for the floats sponteously die,
or Main Street unexpectedly opens up like Aladdin's Cave of Wonders.
(In other words, they are pretty accurate.)
Disney is amazingly accurate and consistent with their start-times.
