Like mom2rtk stated the Christmas parade is sort of unique in that not all parts are adequately lit. I shot it with one camera with my external flash mounted and kept switching it on and off. It got so confusing causing me to miss some shots. If its possible, I would shoot it with two cameras, one with flash and one set up for no flash. I understand not everyone has two DSLR's, however that is what I found to work best. Otherwise, my recommendation would be to be selective on what I shot. I was so busy switching my settings that I did not fully enjoy the parade. I am very much pro Disney photography, however remember we are there to enjoy the activities. As far as lenses/settings I would select either the lighted or non-lighted portions and choose accordingly to obtain the best results.
