we were there in March and we did see the fireworks for both Universal (Much closer) and one of the Disney parks (no idea where they were coming from). We faced the quiet pool - you would have to face this way. We were also on the 4th floor (you'd need to be high up to see them). But I can tell you they were FAR away! Not quite the same magic as being there but nice I guess to sit on the balcony and watch. You are "fairly" close to the parks.....about 10 minutes with NO TRAFFIC!
It's a lovely resort. The pool bar is great and the rooms are nice. There is a resort waterpark being built right next door so construction but didn't bother us at all. Let me know if that waterpark is done when you go!
