We stayed for just one night at HWS Lake Buena Vista (on 192 by entrance to Celcbration) in 2002.
Unless they have done a MAJOR renovation, I can't recommend this hotel. Our room was threadbare - really in need of redo. We could not open the pull-out couch. The frame was bent. The carpet was well worn and stained. I wasn't overly impressed with the cleanliness. I was extremely glad to be leaving after one night!!!!!!
The common areas were a lot nicer than our room, so maybe if you could get a recently renovated room, it would be fine. For me, even at $35, it would not have been worth it to spend a vacation there.......
