This is a member resort but they do allow the public in. We went in as Coast to Coast members. This is an all season resort it does have a ski hill and accommodations for winter. You can buy a condo resort, Lease a Time Share, buy a camping site ( with a Park Model on it, Camp in a Motor Home, Trailer or Tent. You can camp with full hook ups or as they call it the Wilderness Camping, they have some with 110 hook ups.
Facilities are very nice and clean, Swimming Pool, Club House with a lot of things to do. The sites are nice and big most are either pull through or large back in sites. They also have an 18 holes golf course, since we don't golf really don't know how it is.
They have some WIFi but it is best at the club house the hotspots worked better.
If you would like to visit Wisconsin Dells this is a great place as it is not very far from downtown and all the activities. We spent 2 days exploring the Dells even in rain. Had a great time.
If you are in the area I would check it out.
