Yes you can, THVs are part of SSR. I believe with DPs you may make your reservation as early as 7 months before the check-in date you'd like but double check that with MS.
THVs are located closest to Grandstand section at SSR, will sleep 9 ( master has queen bed with full private bathroom, and there is a bedroom with bunk bed to sleep 2, another bedroom with a queen bed. There is another full bath as well and living room/dining room/kitchen combo; living room will have a pullout sofat to sleep 2 and pullout chair to sleep 1.
THVs are same number of points per night as 2 bedroom villa at SSR.
CONGRATULATIONS &
