Planning our 4th trip to WDW. Last time(2003) we went before Christmas. This time we are going to try before Easter. Any advise for this time of the year. Are the crowds heavier before or after Easter. Also, at the time we go I'll have a 9 and 11 year old. I was thinking of purchasing a 10 day pass with the no expiration option. Should I just get the 9 yearold an adult pass?
