The closest one I know of is Westgate Lakes (a 5 star resort) that is on Sand Lake road just off I-4 a couple of exits from Universal. their exchange company is Interval International.
beware, they are just horrible into forcing their guests into sales pitch meetings. a.k.a. "free breakfast" and if you refuse, they can be downright threatening. never mind if you own a timeshare already, they want you to buy ANOTHER one.
btw, I own at Westgate Villas.
