This is our first cruise, and we don't really fly much either. We are driving down from Fort Worth to the Celebration July 26 in Galveston. Does it matter how big your carry-on is? I have a little rolly small one, that would be good for carry-on, but I didn't know if Carnvial is picky about particular sizes or not? It is just your standard looking carry on size. Can anyone help? Thanks and Happy Cruisin' Ya'll!!
