While DD was 3 on our first cruise, she didn't like the club so spent all of her time with us other than that hour she spent there with her brother. We didn't pick DCL for an adult vacation though, we picked it because it was great for families. While DS5 would have stayed in the club 24/7, we spent lots of quality time with DD. DH traveled 50% of the year, so this was the first time in a long time that she had him with her for 7+ days. We didn't start going to the nightclub until our 9th cruise on the Fantasy when the kids were 11 & 13. DD never did take to the clubs and had to be talked into going during Palo, but when we cruise with friends the kids stick together.
