Most RVers pay full price for campsites, but here’s what blew my mind: campgrounds have “ghost inventory” of 15-30% more sites than they advertise online. These are overflow areas, seasonal sites with temporary vacancies, or premium spots they hold for walk-ins willing to pay extra. A former KOA manager revealed they make 40% higher profit margins on these “hidden” sites because there are no booking platform fees.
The secret timing that can save you $20-$50 per night? Call between 3-5 PM on your arrival day. That’s when campgrounds know exactly which reserved guests are no-shows (industry average is 12-18% daily). They’d rather rent these sites at a discount than leave them empty, but online booking platforms don’t allow last-minute price drops. One couple I know saved over $2,000 in a single year using this strategy during a cross-country trip.
Here’s the insider approach that works:
- Book a backup site at a budget campground
- Call your preferred (expensive) campground at 3-4 PM day-of
- Ask specifically about “any cancellations or overflow sites available tonight”
- Mention you’re “flexible on location within the park” (code for accepting less desirable spots)
- Be prepared to arrive within 2 hours (they won’t hold discounted sites)
The psychology is perfectβyou’re solving their problem (empty site = $0 revenue) while they solve yours (cheaper camping). State park managers especially love this because they have strict occupancy targets to hit for funding purposes. Just don’t abuse it by no-showing on your backup reservation.
