I was in that pool less than 24 hours ago. It's open....bring a wetsuit. My kids turned purple riding the slides and playing in the sand. I was ok in the whirlpool for a little as long as the sun was beaming. It's doable, but I can't say it was really enjoyable. I doubt it would close because it was open on Sunday as well when it was about 40 degrees out. I didn't go in but saw some nuts running out.
