Labadee - Aqua Park OR waterslide?

My wife and I are 35 and are considering these. In the past we just did the banana thing that you ride on (which a boat pulls). We liked that. We remember seeing an entire waterpark on the other side but we never did anything over there.

I see that the aqua park (ZL01) costs $15 and the book says "1 hour approx". I am not sure what that means. Do they kick you out after an hour?

Also the Water Slide (ZL15) costs $20 and is "at your leisure"

Thoughts/experiences/advice appreciated.

You should definitely wait until you get to Labadee. You can purchase tickets for both/either the slide or the water park when you get there.

The water park is designed for young children. It is a VERY small roped off area with inflatables to climb on. The only adults I've seen there are parents of the smaller children helping them to climb.

The water slide is a huge inflated slide. There is only one slide. At various times of the day the line can be VERY long. There are adults and children using the slide. You can purchase tickets right near the slide... for either a single time or an all day pass.
