I’m a former NPS worker. Once Recreation.gov became the go-to for site reservations this became a problem. People really do reserve any and all dates they might maybe, want to, possibly camp. The severely underfunded NPS should have better control of the site and rules in place to give everyone a fair crack, but contractors and concessionaires are increasingly getting more control of what goes on and they don’t care a bit as long as they get paid. Last I checked, you couldn’t get a walk up reservation at the Olympic NP Wilderness Info Center AT ALL. It’s all on recreation.gov
