Our family had a blast searching the house for the secret doors! It was such a fun, unique way to spend time together with out-of-town guests. We'll definitely be taking more visitors to the Mansion on O Street.

The staff was super nice, it was great to get some initially info about the Do's and Don'ts of the tour. They gave enough info to pique the curiosity then set you free throughout the mansion. Definitely has you looking through every book and cranny, while admiring some of the famous figures who stayed within the hotel. Definitely recommend this to everyone in the area or visiting! Thank you!

So fun! I spent about 90 minutes searching through the mansion for secret doors and had a blast once I sort of figured out what to look for. There were definitely dozens of compartments I didn't find, though I think I wouldn't have the patience to come back and really search. This spot is great for kids too, and the staff is very friendly. Highly recommend!
