We stayed last summer when the main pool was closed and under "maintenance" but the splash area and existing slides were open. The "adult" pool was closed until this year for a complete "family" renovation so I am assuming that is where all of this is located. If so it sits apart from the main pool area.
We are heading down in June so I'm curious about this as well in case we want to set aside some time for this. (We are staying in a MVC unit a quick walk to this area.)
