My parents are sailing with us in September. We are Castaway Club members and they are not. When we check in, can they go with us in the line for members or not? Since we have separate cabins, we'll need to have a different person checking us and them in and I don't want them embarrassed when/if they are told they are in the wrong line. They are in their mid-80s and I don't think the check-in person would tell them to go and get in the regular line, but I wanted to make sure.
