Pool/Slide Hours in March

[Jkpark]

I am sure this is here some where but I have searched and can't find it

What are the general water slide hours at resort pools in late March? We don't land until 5:30 so I'm wondering if we will be able to make it? And what time does the life guard arrive to open the slide in the morning? We are staying at the Boardwalk for one night before our cruise. Starting to plan the details.

Thanks!!
