When we did our first WDW and cruise this last DEC01, we did WDW first and then the cruise. If I could do it over, I would have done the cruise first and then WDW. The reason is the time difference KILLED us. When we left L.A., we took a 7:00am flight so we had to get up at 4:30am to be there on time. By the time we reached Orlando, we were tired, hungry and cranky and it was only 4:00 pm Orlando time. We had already bought tickets for the Very Merry Mickey Christmas Party at the Magic Kingdom. So by the time we left the MK and made it back to our room at 12:30am, we were totally useless the next day. We never made it to the parks before 12:00pm. There is so much to do at WDW! Even though I tried to start our days early, we just couldn't get going. If we had done the cruise first, we would have had time to ease in to the time difference without being rushed.The cruise was wonderful! My family and I would do the cruise again in a heart beat. As for WDW, you need at least a week or more to do most thing without being rushed.
