On Harmony a few weeks ago they had a binder with the scheduled activities for each day that they suggested I look through/take pictures of (in the aquanauts group). Since our son was 3 they also gave us a form to fill out so they could check out a ship phone to us in case they needed to call us for an accident, etc.
The open houses should be listed in the daily planner. They will individually go through with you the rules, expectations, what included, what is charged, etc.
