I am sailing on the Conquest March 21 with my 12 year old son and 7 year old daughter. I have not worn my thong bikinis with out my little back dress (not sure of the actual name, but it makes it look like you are wearing a skirt instead) on cruises. I have Venus swimsuits and they have matching back dresses and maybe you could still get one in time if you chose a little more coverage. I have been on 2 Caribbean cruises and have not seen one thong bikini yet. I myself don't feel comfortable that exposed in front of my children or anyone elses, and at this time of year, there are lots of kids cruising. I use it more for tanning @ home. Good luck and have fun! Only a couple more days to go!
