We stayed at Summer Bay for 4 nights December 1999. We paid $99 for 4 nights in a one bedroom but even at $25/night, we were disappointed. We had just spent 6 days on site at Dixie Landings and the move off site was a shock! We were in one of the older villas since the new ones were not finished yet. There were roaches in the kitchen and the Jacuzzi in the room was so loud we had to wear hearing protection while using it. On the 3rd night, our neighbors that shared the outer foyer between the one and two bedroom units locked the outer foyer door so we could not get in. This door is only supposed to be locked when the 2 units are used by the same party. It took an hour before we found someone with a master key to unlock the door.
Our disappointment was clear to the sales person, but he managed to waste almost 4 hours of our time anyway - not the 90 minutes we were told before we booked the package.
Summer Bay is a long drive out 192 from Disney. Since this trip, I have found that Priceline proved to be a better way to experience Disney on a budget.
