My wife and I are 28 and 35, respectively, and have 2 children. Lucky for us, however, the kids has prior plans, so we were free to have a "couples holiday vacation" for the first time in years!
Embarkation -
We arrived to Port Everglades at about 1:30, and were the only ones in the AQ line to check-in. Took less than ten minutes from arrival until boarding the ship. There were at least ten separate lines to check-in, and probably 30 representatives checking people in, so I'm not sure they could have done any better than that.
