My wife and I have had a Spinnaker T/S since 1993. We purchased a week in Hilton Head that year at a sales presentation, and had always been happy with our ubit and the service.
Approx. 4-5 years ago we upgraded to unit at Waterside, same week, bigger unit, bigger family, friends, etc. All was well.
Two years ago our week didn't fit into our kids sports schedule as well as when they were smaller. Per chance at a "sales upgrade" we were presented with a "floating week" T/S. Guaranteed to have accommodations up to a week prior to travel. Just the kind of flexibility...
