Because sites are booked months ahead, a steady share of reservations get cancelled as trips fall through. Each cancellation instantly returns that site and those nights to the official calendar — first-come, first-served, no waitlist, no announcement. Refreshing the booking page yourself, every few minutes for weeks, works in theory. In practice, the people who get these sites are the ones who hear about the opening first.
