We almost bought one of the new units...
We were there in January and they are technically not ready because they have not been renovated to the Westin standards, but the buildings are there. After going through the manager, they were going to allow us to buy in one of those units. We actually had the contract ready and everything, but decided not to do it (it would have been our second week in St. John and figured we could buy cheaper somewhere else for a second week). The views are really great from these units and once they are renovated should be pretty nice. I can't remember the hotel chain that owned them previously. Anyway, the salesman told us that they were starting renovaton and by early 2007 the first phase would be finished (he got into trouble for giving us this info!)
I am hoping this will make it easier to switch weeks if we ever have to do this in the future. I just tried switching to a one bedroom from a two bedroom and they told me they were completely booked for Jan-April.
