    Honestly, I did not know what to expect from this experience. I booked it as a mystery day to surprise my mom and sister as we are big Amazing Race fans, love escape rooms, and travel. This experience combines them all! We had so much fun exploring parts of Boston we had never been to before. The day flew by, we were having so much fun. I will definitely be booking again! I highly recommend this experience and can't wait to try it in another city!
