I'm treating my kids and grandkids to the cruise. I will limit the seapass cards for the grandkids to $15/day and the adults to $25/day that charges my credit card (if I can do this). I guess that if the adults or grandkids want to do something more, they can go to the customer service desk and pay for what they want and have it put on their seapass cards. I was wondering at check-in at the terminal if I need to be with seach stateroom occupant and make sure that the limits are set and that my credit card is charged.
