If there's one family guaranteed to put a smile on your face, it has to be Neil Patrick Harris and David Burtka's. On Monday, the brood took a trip to Disney World in Orlando, FL, and judging by Neil's Instagram videos, they had an absolute blast. In one of the clips, which Neil captioned, "Big Thunder Mountain Railroad with Harper. I think she enjoyed it," Neil and Harper are seen screaming at the top of their lungs while riding Big Thunder Mountain Railroad. In another video, Gideon is shown attentively taking in the It's a Small World ride. We've been seeing a lot of Neil and his family lately. After going all out in Old Hollywood costumes for Halloween, the twins attended their first football game, and more recently, the adorable foursome stepped out together at the NYC screening of Disney's Moana.
