We started volunteering at GKTW this past December. Wonderful place!
And while it does have a couple of cute rides, play areas, a small miniature golf course, and a zero entry pool it is, as Goddesstree notes, more of a resort. Most of the 79 acres goes to housing for the families. They recently opened a multistory building with additional 2 bedroom condos. And they just celebrated their 30th anniversary.
They survive with the help of volunteers so if you are in the area or just visiting, consider donating some of your time.
