I'd love some info on this as well. As I watched it Tuesday on our morning show I noticed that the parade stopped and hoped I could get suggestions for viewing!
The parade is AMAZING!!!! Anyway, a great spot is where the Lion King float stops (I got that one) and for the second time the parade stops, it's right before the hub on Main Street, so a good place to be is somewhere along the straight area in front of the Plaza Inn and Plaza Pavillion area. Plus from there you get a really good view of the first float in the first stop.
"so a good place to be is somewhere along the straight area in front of the Plaza Inn and Plaza Pavillion area.

The last float with the Princesses and Mickey/Minnie stopped a little forward of that closer to the photo shop.
