Want to cruise a 7 night but it will be just me, DH and DD5. She is sort of shy but so used to being in camps, school, sports,etc that going into the kids room will be fine. I just hope she has fun. NO one will vacation with us at the time we are going or our second choice of time to go (Sept/Oct or Jan/Feb). So its just us. We did a norwegian cruise with our daughter when she was just 24 months old and it go boring at the end since she screamed when we put her in the kids room for the 1/2 hour the one time we tried and she was too small to do most things. She was scared of the water at that time too. She now loves the water, will need use to hold her or a life jacket but loves it. Will go into play room but might take a while to warm up to other kids. I just don't know if we should do a 7 night or 4 night since its just her by herself.
