Depending on your room location, you may get a decent view from your balcony. We had studio room 5111 a few years ago and it was just perfect. We did go down by the boat dock to watch once, but every other night we watched from our room.
It doesn't hurt to make a room request for "view of Electrical Water Pageant" (like we did) and hope for the best, if that's something you're interested in.
