Bring granddaughters on a cruise. They are 8 & 11. Both are very shy. Can they be in same group,? If not I guess they will not be enrolled.
When you get onboard, you can ask the staff if they can be together. I would also note that depending on the time of year you are cruising, often times their two age groups will be combined based on the number of children onboard. It never hurts to ask if they can be together but sometimes they may not be able to accommodate.
