Here is an arial view of the TTC & Poly (thanks to Chester for resurrecting this). The circles in the Blue represent views from the Grand Floridian and the Poly. The red circle represents one of the view areas from the TTC. It looks like (and according to my DH who did this last year) you can get off the monorail at the TTC and turn to the left and you are right there on the path before the participants get to the MK. After the participants pass there you can walk over (or catch the monorail) to the Poly or GF for another view.
