We are owners at BC and will be there May 15-24! From our past experiences, we have never had an issue with noise from construction. We have stayed in buildings 3,4, and 5. We've had different views in each building and have enjoyed them all, although we have never requested a specific view (this reminds me to call tomorrow to find out about that!)
When we were in building 3, we had a parking lot view. Not the greatest when sitting on the balcony, but we liked the proximity to the pool bar! We had a water view from building 4, which I LOVED. In building 5, we had a fireworks view which also overlooked the parking garage. That view was nice, too, since we could see both Illuminations and Wishes from the balcony. We also had a very clear view of DTD. Bonnet Creek is definitely close to DTD.
I think we're going to try to request a water view in building 3 for our upcoming trip. I'm not sure if we will be able to see fireworks or not from that location. I suppose it may depend on what floor we are on.
