Ask for a high room facing Epcot if you want to see the fireworks. You are walking distance to Epcot (5-10 minutes) so if you can't get a room facing than you could just walk into the back gate a watch from the bridge between England and France. You are also walking distance to Disney Studio (20 minutes).
Be sure to check out SAB pool and Boardwalk. Beaches and Cream is one of our favorate places to eat at Beach Club.
You'll have a great time.
