Thank you Luisa,
The information will be helpful. Luckily my mother-in-law and brother-in-law are going to come too so babysitting shouldn't be a problem. Do you know if Carnival offers a military discount for US military or other cruise lines that do? If they do is it worth it? Sometimes a military discount is more than what other people pay for the same service

Thank you for your help and we're really excited about this cruise. We've taken our daughter all over Europe since she was four months so I think it will be ok, like you said just bring lots of stuff!
