My 2 girls are ages 5 & 8. If I understand things correctly, they would be in different groups in the Club. Please correct me if I'm wrong. Secondly, am I correct in that the 5 year old can not "step up" to the 8 year olds group but the 8 year old can "step down" to the 5 year olds group. If the 8 year old does step down, does she have to be in that group for the whole cruise or can she alternate between her own age group and her sister's group? Thx.
