Well, you can SEE it, but it does NOT feature the MUSIC when it "performs" near MK.
They don't play any audio for MK (I assume) because it could cause too many people to run to see "the show" and that could cause problems with loading boats and buses in that area near the lake.
But, its a simple matter (and no charge to anyone) to jump on the Resort Monorail and ride to the Contemporary, Poly or Grand Floridian and watch the EWP (with the soundtrack) from those resorts. Or take a boat to WL or FtW and see the pageant from there as well.
