OR for Pool bookings?

I'm curious if anyone has used OR as a booking mechanism for pool use. We have an HOA pool that we are trying to reopen. We need to have a way to monitor capacity, so we are exploring our options. If you had occupancy of x number of people per hour, it seems like you might be able to set this up in OR, and thus create a corresponding door tag and guest entry. Thanks!

I don't think OR is going to be able to help you much here - the system is designed to keep track of overnight reservations, not shorter time segments like an hour here or there.
