For those of you with reseverations, what activities do you hope to do in St. Kitts?

We are going with two of our boys in January and have an all day tour booked with Myisland Tours w/Javin and have the all access pass reserved for jet skis and other water activities are St. Kitts Watersports next door.

I am curious what the Park Hyatt will offer. I emailed and they said they have Camp Hyatt for $40/day per kids but I don't think we will do that since we want to spend time with our boys this trip. They say something about journeys and the spa, but I have not seen any pricing and that makes me a little nervous.
