Stayed in a 3 bedroom last December. I won two weeks on SkyAuction's ready-set-go for under $550 for both weeks. It is a great price for accomodations. The hallways were dirty, and garbage was about.. The room was surface clean, furnishings were in just OK shape. High Speed internet did not work (wouldn't have cared - but had to go to Kinko's to send documents to office) and I was charged for it. I called the day prior to the end of my first week stay to make sure my room keys would not be deactivated as my second week began - was assured all was OK - and sure enough - I came back from a long day at MK and could not access my room.. Housekeeping had all their supplies outside the door waiting for me to check out. The pool was OK - but not a resort feel at all. I also did not feel too secure coming and going here as there is no gate or guard at the entrance. I would not stay there again.
I have stayed at Orange Lake and the Embassy Resort at Grand Beach for comparable rates and have been very pleased. I recently returned from a stay at Summer Bay. The resort itself was nice, but I also had numerous cockroaches in my room. Housekeeping was very gracious, and they sprayed the villa twice during my stay, but I was still finding live bugs at the end of my stay. I have stayed at more than a dozen different hotels and timeshares in the Orlando area, and rented three homes, and the bugs at Summer Bay were the first I have encountered. If I could get past the creepy crawly memories, I might give Summer Bay another chance.
As others have said, everyone will have different experiences. I enjoy reading a variety of views when researching my vacations, so I thought I would post.
No mistake about it though, if you are in or near Disney - it is a good day.
