I agree with Stircrazy. This is really not much different than most other short term rentals. Cost per day is cost per day. The majority of short-term sites do not have a lot of fees (at least that are visible). There is a daily rate. Sure, long-term sites may factor in water, electric, sewer etc. but that doesn't sound like what we are talking about here. If I google "campground booking software" about a dozen companies come up. But I would say the majority of privately owned campgrounds still use a simple form on a web page. If I were looking to start a small park, I would figure up all my costs - land, infrastructure, utilities, etc, and what would I need to start making a profit in 5 years. Your rates need to be competitive, and your campground needs to be a destination with good reviews. That's the focus. Booking software would be an afterthought. A nice website with a phone number and excel spreadsheet is how a lot of parks start and still operate today. As I said, most have a form on the website that feeds the owner an email, spreadsheet, whatever. Years ago, we had an RV rental business. VERY busy. But all we had was an ad in CG, FB marketplace, a website and a form that shot us an email with a reservation request. Worked for years. For a small campground, booking software seems like a solution in search of a problem and something that could wait. But that's my opinion and worth exactly what you paid for it. :-)
