We stayed in the BWI twice and loved it both times. This past June we had a standard room (4278 or 4287) with a fabulous view of Epcot. We were able to see the fireworks right from our beds. Below us were the BW Villas with beautiful flowers. It was a peaceful and great view.
Our first visit we were on the Boardwalk side overlooking the boat dock. It was also a great view, but it was kind of noisy with the activity on the boardwalk below us. Our son was young during that first visit so we got to bed rather early.
As others have noted, the Epcot resort area is so great for a lot of reasons. So many great restaurants to choose from. Check out the menus on allearsnet.com....go to dining and menus for the Boardwalk, Beach Club, Yacht Club, Swan and Dolphin. It is so nice to be able to walk or boat to both Epcot and the Disney Studios. The entertainment on the boardwalk is a lot of fun. One day when it rained we found that they moved the entertainment to the lobby of the Boardwalk.
One tip I can give you from our June visit.....We were at the BWI for eight nights and were getting tired of going out every morning for breakfast. We saw the sign for the Belle Vue room just before the elevators on the lobby level. We tried it for breakfast and loved their selections. They have muffins, bagels, donuts, assorted cold items along with coffee, juice, etc. We enjoyed taking the food back to our room and eating breakfast up there before heading out for a long day. I also thought the prices were pretty good. They have seating areas so I believe you can also eat right there if you want to.
The BWI is definitely on the top of the list for our next visit to WDW. Great resort and great Cast Members.
