This will be my first cruise and my 11 year old daughter's also. I could use any advice available from all of you seasoned cruise veterans on what excursions to do in each of these ports. My daughter is a good swimmer, but I am worried that she will not be able to participate on some of the "children under 12" tours. How strictly do they enforce this age limit? My daughter could easily pass for 12 (don't tell that to your 13 year old son, please!) We are sailing with RCI on the Nordic Empress. Tell me, will we be impressed?
