I don’t think there is a restriction. There is a max limit of vehicles, three I think.

Thanks for this confirmation Steve, I will update my note on the blog.
While I certainly appreciate that $300 is a lot of money for a campsite, as far as we’re concerned, the less facilities the better. It’s true this can be an issue with high traffic sites, but it’s the same reason we’re willing to pay for “nothing” at a Special Campsite in the Serengeti that is also just a piece of Africa and nothing else. Many campsites we’ve been to are ruined by bad facilities, or faciliteis located in terrible spots (long drops obstructing the view, that kind of thing), and campsites with great facilities no longer feel like you’re in the bush. Just my .02c, of course at different times we want all the trimmings!
