I am taking my 3 year old daughter on 13 day cruise to Italy, Croatia & Greece. There are a total of 6 adults and my 3 year old going. I have no other choice but to bring her since I am a single parent. At first I was a little apprehensive, but now that I have done my research and have tried my best to prepare for this experience I am excited - as is she!
I say go for it! You only live once.
