I had a cabana the only time I went to Atlantis, and I don't think I would have enjoyed the day without it. Your experience will greatly depend on the time if year you go, we went during spring break, and the place was packed. They don't allow you to walk through the water ways without a float, and those were super hard to come by. My youngest and I only snagged a glistening once, my oldest got one twice, and my husband never managed to get one, so he never made it through any of the slides. The food/drink lines were over a hour long. It was extremely nice to know that even though we couldn't really do any of the slides, we at least had a place to sunbathe, keep cool, and that we didn't have to wait in line for food, and that we had lunch and drinks delivered to us whenever we wanted.
