Before saving seats for any parade you've got to check and make sure you're not sitting in a special viewing area. These are marked on your map; you should also check to see where the stantion "holes" are (that's where they'll put the poles with ropes to block off the area) The CMs only set these up 1/2 hour or so before the parade, and you will be asked to move.
Saving seats is such a hot topic! Some people think it's OK for one person to save 20 feet for their group of 20;others think it's rude to save your husband's spot if he runs to the bathroom!
I remember saving a bench in Epcot to watch Illuminations. My brother, father, and daughter were riding Norway and Mexico. My mother, sister-in-law, and myself were saving the bench (1&1/2 hour before the show) We were at each end and in the middle, with our "stuff" in the spaces. You would not believe the number of peole who truly expected us to move so they could sit down!
Were we being rude? We were willing to forego having fun to sit there; why should someone who just got off of a ride expect us to just give them a seat?
I've seen people put down whole blankets to mark their spot, then just walk away and expect others to honor it...I consider that unrealistic. But if I see 2 people sitting with a towel or "stuff" between them, I assume they're saving that seat, and would never ask them to move. I would also never walk over their things to cross the road etc.
I hope I haven't opened a can of worms here! :lookaroun But I didn't start the thread!
