What you are being offered is the studio side of that lock-off. If your maintenance fee quote is correct for that week, I think that the MF is too high for what you're getting.
You have the smallest room type to rent out, and it is less desirable for families because it lacks a full kitchen. I think you'd have a hard time renting it to cover MF unless you can rent out week 7 or a holiday week, but check the contract first. I think Westgate sold those as fixed weeks, so you may be prevented from even booking them yourself. As for selling, forget it. Westgate strips any kind of benefit from resale owners.
The room is a studio. Yes, it's a very well-designed studio, with a separate bedroom and a workable kitchen area but it's still a small room. There is no washer/dryer in the room. Only a kitchenette vs a full kitchen on the other side. I stayed at the Westgate Park City for a week of skiing in February. We had the two bedroom lock-off unit. The property was very nice and I was impressed. My teenaged-son told me it was his favourite time share ever!
Would you want to spend a ski week in a studio unit? The separate bedroom makes this more doable than the Marriotts which really lack in their kitchenettes but would still get crowded very quickly. I wouldn't stay in the studio unit with more than two people, even though it sleeps four. So it is less rentable than the larger one bedroom side of the lock-off. Unless you want it for your personal use, I'd personally pass. The high MF makes it unattractive.
