My wife and I did a room on a date night. Our only mistake was that we booked a hard room which would usually require 6-8 people and there was 2 of us, so we weren't successful. But it was a really neat experience that tested our minds...will try again.
Best part of our date was actually the cafe after, which wasn't all that special other than they had hundreds of board games which were a lot of fun to play while drinking coffee. In a world where we are attached to our electronic devices this was a refreshing evening as a couple where we truly unplugged and had fun together.
