We are in the process of booking a 4-night cruise for mid May. Our youngest, who will be three at the time of sailing, is not fully potty trained yet. We expect to have her rearing to go by the sail date but were a bit unsure as to the policy/general practice for the Oceaneers Club when it comes to this issue. Are we going to be required to sign up for the Flounder's Reef Nursery Group if she is not full potty trained?
