This is exactly the thread I was looking for - I'm planning an October 2020 trip for family of 7, and was considering a rental at the campsite. We are a large family, and we've never all stayed in an RV or trailer before, and I am kind of clueless on sizes.
Based on the research I've done the last couple of days, I think I understand how it works - we book the campground, rent the RV, and when we checkin we'd send the information to the RV rental company, and they come and park it and do all the hookups, and then on checkout day we just tell them what time we are leaving and they handle any waste water and detach? What happens if we screw up and reserve a spot that doesn't fit the RV we rent? This is kind of my big fear! Also - we have a large 12 passenger van, and I'm worried about the RV and the van both fitting at the site, especially if we also rent a golf cart.
I'm pretty overwhelmed (in a good way) with all the options, so if there is a FAQ or another thread for me to read, I'd love the links. Thanks!
