Of my six cruises on DCL, all but one have been adults only (bad, I know...well, not really!). We did our first cruise in 2000 with DH's daughter. Since then I have also cruised with my mom once, and with one of my closest girlfriends once. So, as you can see, my cruises have been all over the board as to who I have cruised with! Go for it! Every single time I have had a great time!
