Our pool does not close. As long as it is warm outside you are welcome to swim.
I don't know, but the Garden Inn Hilton directly adjacent to it has a pool that is indoor and outdoor both that is always open. You might check with the hotel.
Sorry - don't know. We were there in the May, June, and July timeframe.
Not sure. I would try contacting the hotel.
