Well the most recent was when I went to Disneyland, as soon as the train station came to view with the monorail in the center of the two parks, I started balling because I never though I would get to see Disneyland in my life. I cried so many times that day lol it was ridiculous but I was so happy. And several times I've cried in WDW over the years lol.
