Thanks for your response. I read about the toddler time, but it seams that it is only for a short time during the day. It just seems like you are very limited when you are on the boat with toddlers-now if she was over 3 it would be a different story.
The reason we are going is my husband has a convention on the cruise...very cool, but that means it will just be me and her most of the time during the day. I just don't think I can do it without the pool-its an eastern caribbean cruise. When I imagined our week cruise, I figured her and I would be in the pool or hanging out near it the whole time. And that means that my husband and I will not be able to swim together. I'm super bummed.
