Room Assignments - correct, the hotel assigns any room that is available. As you mentioned, they own and rent out quite a few of the one and two bed units, so you can end up in any that are available. I didn't think the HGVC ownership was as low as 16 units, but that could be the case.
Room Views/Types - the rooms were in fact purpose built, not a hotel room conversion. However, they are more compact that most HGVC resorts, but as I posted above, I think well designed and laid out. Yes, 4 in a 1-bed may be a bit tight, but certainly doable. As to views, I think you may be mis-remembering as a) all resort parking is underground, under the resort (there are no parking lots around the resort, save for the largish Porte Cochere area where sometimes valet parks a couple of cars; and b) the resort has a road on all sides. As to views, one side faces the driving range (but between that and the resort you have a small little cactus garden/park that is part of the resort as well as the road, on the other side you face one of the course holes, but there are trees and a couple of other houses blocking any view (again, over the road). Bottom line, this is not a resort for "views" of any type in my opinion.
