Laugh Floor is a fairly overlooked attraction at Magic Kingdom, and quite honestly, I can't see why. While it's not an amazing attraction, it is certainly great fun.
For a comedy show relying on the same gags and skits every show for the past few years, it still remains funny due to the greatest aspect of it: guest interaction. The different responses from the audience change the show just enough to remain a good time. The actors put in a lot of passion into their roles and are wonderful at improv.
It's not perfect, but it's still a great time if you can fit it into your day at Magic Kingdom.
