Been on two RCCL and had daughters in their 20's with us and they had a great time. I did hear on our last cruise (a week ago) that the Panama trips usually have older folks on them, not sure about this! Ever think of trying Carnival. We are in our late 40's, hubby is 50 and we just did our first carnival and booked another one already. Found it to be more fun, not rowdy or the horror stories we heard in the past. We had a great time and seemed more upbeat. Food was definitely better.
Have a great cruise whichever you choose!!!!
