Wyndham Bonnet Creek (the timeshare resort, not the Wyndham Grand) is the one everyone LOOOVVEEESSS (us included), for the low prices, great amenities, and beautifully appointed and spacious units. I would certainly look into it for a weeklong stay as I find a hotel room sort of cramped. Check out the first page of the "loooveee bonnet creek" thread for rental options - we used Farrell Pickering (google it) and had a great experience - around $160 per night in a mid season for a 2 bedroom. We also got a quote from Vacation Strategy but Farrell had a better price and better availability for us.
We have stayed at Hilton bonnet creek and also really liked it - but after resort fees and parking, the price was more than our 2 bedroom at Wyndham bonnet creek (and Hilton was just a standard hotel room, albeit a nice one). The reason we love the entire bonnet creek area is for proximity to the Disney parks - if you are not visiting the Disney parks, the convenience factor won't be an issue for you. Both the Hilton and the Wyndham timeshare resort have great amenities that would make them wonderful getaways even if they weren't essentially on Disney property, but you might check out other areas of Orlando as well.
