We had a PS for 8:20 I think. We got there around 5 min. early and requested a window view. They tried, but we were on the second level about 40 feet from the windows. It was neat seeing the low fireworks. The music is piped in. If we would've had a window seat it would have been great. You miss a lot of the fireworks off to either side. The noise of the fireworks going off was the amazing part to me. They seem to launch them right outside the windows. So I say, your chances of getting a window seat are not that good 15 minutes out. I would try to go a lot earlier and let them know of your ps and your wish of a window seat for the fireworks. The worst they could say is no. Good luck!
