Anyway, since I am a bit of a solitary, this was a lesson well learned and I will try to avoid such places in the future.
If such a vantage really is the best place around for observations, and if you're not entirely put off by the mob scene, you could plan to arrive earlier the next time. If there is a next time. The situation sounds rather absurd to me, but then I tend to avoid crowds unless I'm shooting them. To me, finding a full parking lot means it's time to look for another vantage point, or to have fun elsewhere and make an earlier start next week.
Somewhat related: There are time's I've arrived early, been all set up... and nothing happens. Last time was at Carlsbad Caverns. At dusk, millions of bats usually swarm from a certain entrance, which has an observation amphitheatre built around it. So I'm there ahead of the crowd, camera on tripod trained at the magic spot; the crowd fills in; the docent speaks quietly of what to expect. And we wait. And wait. And we get maybe a few dozen bats, total, straggling out intermittently. Apparently the rest sensed a thunderstorm a few miles away and stayed home. Ratz.
So we packed up, trudged back to parking, got in the queue of late-leavers. We headed for our camp site off the main highway several miles away from the National Park. The NP intersects the main highway at a tourist services village called White City. The White City intersection is lit with bright lights. Bright lights attract insects. Insects attract bats. The White City intersection was swarming with bats! They'd come from other cave entrances, or other caves, and THIS was where the action was. Not quite as impressive as millions issuing from the cavern mouth, but the lighting was better here.
