Hi London Girl, I wish you a VERY happy holiday when you go to Orlando, I see you have picked up some excellent advice already. I am sure you will have a wonderful time with your son and the rest of the family, my only helpful piece of advice (well maybe?) would be not to let your son get too tired or over excited, easier said than done in Disney etc I know. But, it is a lot to take in, for a first timer. Wish you well.
