Can we tent camp here? Is tent camping ok in the electrical sites? Don't really want to rent a teepee.....

I didn't see anything that would preclude being able to tent camp at any site. In fact, some would be very nice for tents.

I'm pretty sure I've seen tent campers in the "rv" spots. Also, I believe there are tent spots that are near common electrical outlets.

I can't see anything on their web page that would indicate it's not ok.

I've seen people with tents in the RV Park

Yes

Plenty of room
