A very interesting 2 hours of wondering around the O Mansion. There is plenty of stuff for everybody to see. We weren’t very successful at finding too many of the hidden doors..only 8 of 69 of the hidden doors

I chose this amazing place, for my birthday. My family loved the mansion. The grandkids enjoyed the treasure hunt, and finding secret passages.
