Paradise Springs is, IMO, the best of the "OW safe" cavern dives. Unlike Ginnie Ballroom, there is no flow, so visibility is lower when there are a lot of divers there. As others have said, weekdays are better. Weekends are OK, especially if you get there when the gate first opens.

If you don't have good trim, bouyancy, & propulsion technique, this site will let you know. Also, there is more than one place here that you should stay the heck out of. So be smart and careful, and have some good dives there. I know I have.
