I want to give this place 6 stars out of 5! I have done the Secret Doors tour before, but LOVED upgrading to the Hidden Gems. Having the "score card" to keep track of doors and so many other treasures really inspired us to explore.

LOVVVVED IT! The O Mansion defies description. It's a combination funhouse, decor tutorial, historic architectural tour, video and audio show, brainteaser, blast from the past, gymnasium and yard sale. It's cozy, confusing, creative, confounding and cuddly. It triggers emotions and memories, releases stress, and increases productivity... and creates a natural high achieved by just being in it's presence. This expanding-contracting time capsule is a MUST EXPERIENCE. I found you through Atlas Obscura, but I am certainly willing to tatoo you across my ..., for advertising purposes, so the uninitiated can experience you.

So much fun here! Explored for 90 minutes and could have spent many more hours there. Every time I found a hidden door, it was exciting.
