We have only stayed at Grosvenor so can only comment on that property. We really enjoyed it. The room was much larger with more amenities than a Disney moderate, at a much lower price. And, of all the hotels on Hotel Plaza Blvd. it'sthe closest walk to DD - a major plus for us! After a day in the parks, we just walked across the street (literally!) to DD. I can't comment on the bus service as we always rent a car.
