For some reason the word timeshare turns people off so much.
If this is what Uni is doing, then it's nothing but good for business. Just like WDW, you're LOCKED IN for a set number of years, meaning a constant flowing customer base. There's a reason Disney's DVC's are almost always at 100% occupancy.
Beyond that, if you aren't someone that has bought in, you can still rent a room or pay rack rate. The problem becomes when people focus *too much* on timeshares and not their core business...
