I believe I will at WDW just in time to catch the last SpectroMagic Parade of the summer. I have seen the Parade once before, when I visited in April and I loved it. The music is fantastic, as are all the floats.
I arrive on the Saturday, and the last showing is on Sunday evening so I am getting excited now. The parade is almost always followed by Fantasy in the Sky Fireworks, which is a must-see!
