Marriotts Cypress Harbour is also a timeshare but you can rent out the unoccupied suites.
We stayed there in 2003 and it was honestly fantastic. Great location and many ammenities.......three pools, at least three jacuzzis, clubhouse, onsite store, onsite pizza place, maid service if you are renting only (if you rent from an owner you do not get this).
The unit was clean, spacious and well kept. We had one problem with the air conditioning and they were there within a half hour and this was late at night when we came home. Great lost and found service (DD left her eyeglasses at the pool).
Kids activities in the pool area......
Did not need to listen to timeshare spiel.
Literally five minutes from DTD, two minutes from a large grocery store (I think Publix) and in a quiet area of Lake Buena Vista....easy driving.
Let me know what other specifics you would like and I will be glad to answer.
