We stayed in one 2 years ago.
The villas are beautiful. The master bathroom is spectacular. The large deck outside is a wonderful space and there is a charcoal grill at the bottom of the steps for each villa which is very nice. The 3 bedrooms are pretty small. The bunk beds in the one bedroom are also small, average sized adults would not be able to sleep in them. The kitchen is very nice, the dining room table is large. The living area is small with a seating arrangement that is not set up for you to sit and have conversation. And if you need to use the sleeper sofa, it takes up the entire living area. It's a 3 bedroom but has almost the same sq footage as the 2 bedroom villas so you give up living space and a large master bedroom to have that 3rd bedroom.
They are remote. If you want to feel like you are in your own little world, away from it all, this may be the place for you.
A golf cart is not necessary to walk to SSR. If you are close to Grandstand, the walk is probably 5 minutes from that section, maybe 10 minutes to walk over to Springs, the main section of SSR. If you are like us and are on the other end near the entrance to the THV, you will have a 15-20 minute walk.
There is an internal bus system that will take you from THV to SSR and then from there you would change to a park bus. We tried it once and it was a real time sucker. But it is there.
The pool at THV is like a backyard pool, at least like my backyard pool. For a real vacation/hotel pool, you have to trek over to SSR to the Springs or Paddock section. Since we use the pool a lot, this was a real deal breaker for us.
Condensed version: If you have a car and like getting away from it all, these are nice accommodations. If you don't have a car, I'd give it a great deal of thought before staying here. If you don't like feeling isolated, take a pass on staying here.
I have owned DVC for a long time and we have stayed in all of the villas in various sizes from Grand Villas down to studios. For my family, the THV have been our least favorite stay. We discovered that we didn't like being that far removed from the amenities we enjoy while on vacation.
