There are also views of DTD which would allow you to see the fireworks at DL but we were always IN DL when the fireworks were going on so that did not seem like as much fun. Also this view looks over the street that connects to Paradise Pier hotel, so you would have to be up a bit to not be bothered by this.
We were up pretty high so noise wasn't too much of a factor, and it was fun to see the folks playing in the cool pool.
