My next cruise I'll be toting about an almost 9 month old (and he's pretty big for his age). How do people usually get around when they have infants? I'll have my stroller, but I have a feeling I'll get annoyed having to wait for the elevators. I'll bring my baby carrier, but I do worry about getting hot. Any one have any other suggestions? Any other suggestions on cruising with a baby would also be great.
