Not disagreeing with you on anything here and I've been thinking about the model situation as well. On one hand, it would be even easier to show a model than with hotel rooms, as they can just put an actual unit wherever they want to have it.
On the other hand - really? Putting a cabin next to beautiful hotel buildings? 'For the small price of $20,000 plus annual dues you can sleep in one of these huts instead of a hotel room' I just can't see this having the same effect as walking through models of previous offerings. I guess the cabins 'feel' more in place with trees around them?
