We are taking our daughter and her boyfriend, both 31 years old, on this trip. It's a port intensive itenary, Rome to Balcelona. They are concerned if other passengers are all old like Dad and Mom, and there's nothing for them to do. One reason we are leaning toward Voyager is that it's a big ship with 700 passengers, so we might see some younger people. Would 30-year old be comfortable there? My daughter is quite sophisticated, and her boyfriend is learning.
