In 1998 we use to watch them from the Contemporary. They piped in the music. We saw it from the parking lot once and from the top floor closest to the water once. (The opposite roof was for restaurant only)
Thsi year I took my grandaughter to the Poly beach but we couldnt hear any music. The guy in the store said they do hear music but I didnt hear it so Im unsure why. Maybe I was too far over? or maybe it was piped somewhere else? I was right on the deck next to the sand. Was a beautiful place to see the castle and the fireworks.
