In response to those bothered by "critters," I've said since the start that THV would probably not appeal to two types of vacationers -- those without cars, and people who really don't like being somewhat out in the wild because THV is in a heavily-wooded area.
Cars and Parking:
The cars/bus issue may not be as obvious at it first seemed. It may be that parking is more of a problem than bussing, and if so, I may have to reverse my earlier thinking about that aspect.
Disney can improve the busses, but we all KNOW how guests are going to respond to a one-car limit -- they're going to ignore it. And Disney will not enforce anything, so the burden will be borne by the guests who try to follow the rules.
I'd be willing to bet that
DVC can't add more parking places because parking lot runoff affects the wetlands THV sits on. My guess is the final solution will be parking on the grass.
Critters:
Currently, there are probably a lot fewer critters around THV than there will be in a few months. Construction always disrupts animal habitat and they move away. Once things settle down, they will probably move back.
Realistically, the kinds of critters you are likely to see at THV are racoons, possums, rabbits, river otter, and deer. There will be a lot of smaller stuff, and slithering stuff, but you are not likely to encounter any of those except lizards and frogs. There will also be assorted bugs and bug-like creatures -- goes with the territory.
Most people will not really care much about the varied wildlife around THV. They'll enjoy deer, rabbits, otters, and racoons and they'll be grossed out by possums and palmetto bugs.
But there are a lot of folks who are sincerely phobic about creepy-crawlies. Those folks are honestly just looking for trouble if they stay at THV. It's just the wrong kind of resort for those folks.
