We just returned yesterday from a 7 night stay at the BWI, with our 5 yr old daughter, and it was WONDERFUL! The rooms were large and gorgeous, it was a short 5 minute walk to Epcot, or a short boatride away from MGM. She loved renting the surrey bikes and riding them along the Boardwalk past the Yacht and Beach Club and back again. If you stand on the promenade you can see the fireworks from Wishes, and if you stand over the bridge to the international gateway you can thee the fireworks from Illuminations. The dining choices were great, as well as the free nighttime entertainment.
The WL has been our absolute favorite in the past, but now nothing can live up to the BWI to us!
