Hi SteveBeme!
Boy I understand your frustration! I was in your mental state about 2 months ago. It can be overwhelming to select accommodations. We ended up renting a 7 bed/6bath home with a private pool. There's 9 of us - but all adults & no kids. I spent the better part of 3 days reading all the discussions, trying to get some ideas for our lodging.
We liked the idea of a home with its own pool for our crew. We wanted plenty of common meeting space since it is a family trip - but also some private space too. We really liked the idea of the pool & hot tub right out the back door. No walking several blocks to the community pool.... We actually liked the idea of no maid service, and also having a full kitchen and dining area. So it was easy to decide to rent a villa offsite. They really don't have comparable accommodations onsite right now.
So if you like the idea of home/villa. Then you should really decide what type of bedrooms configurations you want (what size beds) and number of bathrooms, and also the amenities that you want (hot tub, jacuzzi in master bath, TV's in all bedrooms, pool table, air hockey, video games etc). Then set a budget. From there you can start looking at homes. I am completely certain that you can find a very nice home and rent two cars for even less money that 2-3 rooms at a WDW moderate resort would cost you. There's all price ranges though, from as little as $550 per week to more than $3k per week.
There's a management company that has a really good website for research -
www.AllStarVacationHomes.com It will give you a good idea of different neighborhoods and homes. You do pay a premium to rent from them, so consider using one of the websites already listed by previous posters here.
We are renting St. Andrew's Villa in Formosa
Gardens, from owners Franco & Audrey at www. OV4U.com They also have other homes as well.
Once you've decided on # and config's of bedrooms and basic desired amenities, you can post back to get specific suggestions.
Good luck!
