There is a large group area located in section D. This area would be just what you need. The number of sites available are limited. You will definitely need to plan ahead.
You could have found this easily on Google: "Campsite occupancy is limited to eight people, three tents, and two vehicles per site." I doubt you'll be able to fit 5 tents at most sites at this campground unless you booked one that has a lot of space. Some can barely fit one large tent.
I believe it was 3 when we visited a week ago. Though if you had small backpacking tents I'm sure you could talk to a camp host about it as an exception. It's always been a funny concept in my opinion to limit the number of tents per site. A group could show up with 3 massive 4+ person tents and that's ok but 6 backpacking tents, hammocks, or bivys isn't allowed? 🤪
