How do you handle this scenerio? DC will turn three during the timeframe we are considering going to WDW. If we book online, I don't see any option for changing the age. I am not looking to beat the system but how do the parks verify if the child is 3? Do I just call and book through a travel agent or the disney 800 number? DC would be turning 3 the last day of our trip...what a pain!
