I'm a newbie to the board, we are thinking of taking a spur of the moment cruise in November. I know there are alot of onboard activities for children but how do you sign up for them? We have a 5 year old and an 18 month old. We would like to have the 18month old in the babysitting at the same time our 5 year old is doing an onboard activity but how do I time this out right? I know for the babysitting this has to be reserved on the day you depart but haven't been able to find any info on how to get registered for the onboard activities. Any help would be appreciated.
