My concern about swimming late at the Dunes Cove Pool (BCV QP), is the pool lights are turned out around 11pm.
Not sure what the posted hours are, but when we stayed there 12 nights last June and December, we had pool view both times and the lights definitely are turned off.
There were still people swimming (a couple of teenagers), but I dont think they intend for people to swim or they would leave the lights on so you can see the bottom of the pool.
SAB closes completely down and there is no unguarded swimming allowed period.
On several days of our trips, SAB closed as early as 6pm during the week. I asked the Rec Mgr. about the short pool hours and how SAB is not available after the parks close, even when MK closes early. Even in late May/June over Memorial Day weekend, I thought SAB closed too early. They did say they were short lifeguards and it was much harder to guard at night, which I do understand.
We like to swim late, and that is why after last year, we decided to limit our stays at BCV to a few days to enjoy SAB and then move to SSR, which is our favorite place to swim at night, followed by VWL.
