I think this is the one thing people forget when traveling to WDW -- it is still a vacation! Yes, this is a fast-paced, high-energy destination but it is still a vacation! Take your time, enjoy yourself. Go at the pace that makes you most comfortable and you will come home with many more happy memories than if you went in with a commando attitude. I feel so sorry for the families I see that are going a million miles a minute and aren't taking time to stop and smell the Disney roses. Enjoy your vacation! P.S. Don't kid yourself, after your Disney vacation it will no longer be a "once in a lifetime" trip!
