I had to do similar during the first summer of COVID to get my boat onto Lake Tahoe. Lake Tahoe (and most lakes in CA) requires boat inspections immediately prior to getting onto the water (mostly to prevent Quagga contamination). Those inspections had to be scheduled online during COVID, and there was similar supply & demand to what you describe for parking, so I wrote a bot that notified me (also via Pushover) when a slot became available.
Once I got the reservation I had to tow the boat 9 hours, praying the whole time I didn't have a drop of water on the boat, for which most inspectors will immediately fail you and send you away. The inspection crew there turned out to be pretty awesome though, and they actually washed my whole boat down with hot water which apparently kills any (baby? egg? idk) Quagga muscles.
