Were considering a 3-day Wonder cruise in Fall 2008 with our DD and DS who will be 8 and 5. Wed go to WDW for 2 or 3 nights prior to cruise. Our kids would miss less school if we went October rather than November. Some thoughts going through my head are: Is chance of rough seas higher in October vs. November or no difference? Will it be extra crowded sailing the weekend before Columbus Day? Is it possible it will be too cool to swim if we choose 11/13 sailing? What is the likelihood that Christmas decorations will be up for the 11/13 sailing? Our ideal trip would include nice weather, calm seas and low(er) crowds. What would you do?
