Stayed at several of the downtown hotels.
Walking to DTD - Hilton is the closest to DTD. For me, Hilton was the best in terms of amenities, pool, Disney perks. If our entire family comes then we go with Doubletree. It is the farthest but the space of the suite and breakfast (we've had included in rate every stay) were perfect for us.
Have also stayed at Royal Plaza and the Wyndham under a former owner.
