My daughter also saw another, no names, they were entering the park together, we was not friendly at all, she doesn't watch his stuff anymore lolLove Molly's vlogs. Watch them all the time! Glad to hear she's approachable in person. I always wonder if we'll ever run into any of the many vloggers we subscribe to while we're in the parks.
We met Oliver (used to be on the DisUnplugged team) at a restaurant in Universal. He was a server. Very nice!
