I think there are several groups THV will not appeal to.
One is the folks who are not comfortable with bugs, lizards, frogs, and -- dare I say it? -- snakes. Or racoons, possums, squirrels, deer, etc. A lot people really are creeped-out by critters, and THV will be a critter-rich environment.
The other demographic is folks who depend on the bus system. It probably doesn't make sense to have dedicated buses for 60 villas, but to me the bus plans look really problematic.
Also, you need a pretty good-sized party to justify the points cost of THV. I think THV will be awesome for a party of six (8-9, not so much) but I wouldn't stay there with my family of 3. THV would be 60% more points per night than an OKW 1 BR, which suits us perfectly. So that points-cost will eliminate people who could do fine in a studio or 1 BR.
All that said, with only 60 villas, I think THV is going to be a very tough ressie inside 7 months.
