We camped with a group out on one of the points for some good off roading. LOTS of nice trails to go, lots of desert to cover. Some sand, some rocky areas, a nice assortment. When we came back we would hang around the beach. They had a nice store where you could buy almost anything. A nice bar and restaurant, with good food. The only complaint I have is it was a little pricey. $70 a night, granted full hookups, but a little high.
What a fun place for you and your kids! Lots of River activities and ATV trails. If you don't have the toys, they have all types of rentals available for purchase (1/2 day and full day increments).
The cottages were beautiful, the on site restaurant was huge and inviting! There are tent sites, RV sites, and boat docks.
I have T-Mobile, and didn't receive any signal while I was there.
