Put this down as 'anecdotal' but I was talking to a teller at my bank who is going in June. She said they were told they'd get their 'reservation time' when they check in, BUT that (per the booking CM) "if SWL is at capacity when your reservation time comes, you'll be given a 'rain check' for another time". She didn't ask specifically when that 'rain check' would be. Later that day? Another day during her stay? Three weeks from next Tuesday? It'd be a bummer to show up at your time and be told "here's a rain check....come back at 9 pm tonite".
At any rate, sounds to me as if there will either be no 'exit times' and they're just going to hope people leave so other can get in OR that they aren't planning on being strict about kicking people out after their allotted time is up.
