No it's not open. But when I went I had zero issues going in the hot tub and the pool at 1am. The only mild inconvenience was there was a policeman in his car watching us almost the entire time. But me and my gf were in the pool and hot tub until at least 1:40-2. As long as you dont cause a commotion you should be fine.
No it's not, and only one table in the whole pool has an umbrella
No
