In park promotions and scavenger hunts: free stuff and extra fun
Follow Universal Orlando on Twitter (@UniversalORL) and then keep an eye on their feed when you are at the park. They often announce in park "find us" contests, where the first group of people to locate a certain Universal employee (usually standing around in a blue shirt holding a clipboard) gets something extra. This could be a ride on a parade float, a gift bag, or even a front of the line pass. They also host scavenger hunts this way. One follower recently got a free Harry Potter wand!
