We just got back from a stay at BWV and OKW. I never could get online check-in to work, so I wasn't able to put in any requests at BWV. I *thought* I wanted a room close to the elevators and we got rooms 3113 (studio) and 3115 (1-bedroom) = 2-bedroom lock-off. It was pretty far from the elevators! But.... we quickly realized we actually liked that location! We had our car and drove to all the parks (except walked or took the boat to EPCOT/DHS, obviously). We quickly realized that we were close to the stairs that led to the adult/quiet pool. Also quick access to the DHS walkway and the parking lot!
We spent 5 nights in this room. We apparently were never in the room around 9:00 until the last night - Thursday night. (Friday we checked out of BWV and into OKW.) All of a sudden, at around 9:00 or so, I see FIREWORKS through the curtains! We could see fireworks from our balcony!! (And a good view of them!) Well, at least from the balcony for 3115. 3113 was completely obstructed by a tree. Wish we had known sooner that we could see the fireworks from our balcony!
Overall, we loved staying at BWV but wished we had taken advantage of the BW more than we did. One night we happened to catch a little of the entertainment on the BW. Our teenagers saw more than we did (spent less time in parks than we did). Really wish we had spent more time on the BW itself! And wish we had discovered the fireworks from our balcony sooner!
