I'm a single Mom as well and will be taking my 7 yr old on our first cruise (as a non traditional family) in April. We went as a family with spouse a couple of yrs ago, but for all the time he spent chasing young girls, I may as well have been single. I ended up doing my shore excursions on my own with child, and its not a big deal. Just stay with the crowd, and don't wander too far off the beaten track. Everyone on board was so friendly, I am looking forward to doing this cruise for pure fun with my child, and no excursions to heartache land.
