Don't mind that, slots are 1h long with a 15 minute gap between. Last time I was doing long swims I just had a lie down on the side for 15 minutes while they did the changeover, and remembered to check in for the second session on the way out of the pool (otherwise I'd get charged for not turning up).
That's better than 60 people turning up for (effectively) 45 places and it being an utter bun fight.
It's (Better) changed since I last looked and I can now book multiple slots but I still need to check-in for the second slot within 10 minutes of the start time so on the way out is theoretically a problem although perhaps not if I speak to reception. I'll have to ask them.
