I believe I saw tent campers there, but I would call the office to make sure.

As far as I've seen, all sites are full service. However we have been here for the winter (several months) and routinely see tent campers on sites. So while you probably won't get a discounted rate, you should be able to pitch a tent on most sites. Some are actually great sites for tents.

If you look, on their website, it says "yes".

I think. We only camped there one time and were not looking for tent sites. I would phone them.
