In high school, I actually ran into the same family on 2 different trips to WDW. One one trip I saw them at Universal Studios, and on another trip I saw them at MGM. That's quite a feat seeing as we were all from upstate NY and had no idea each other was going to Florida either time. It was my softball coach, his wife, his daughter (my teammate), and his son (my classmate). I've also seen other people from my hometown on several different occassions.
