Denny is phenomenal! I can't recommend his boat tours enough. My business team and I booked a time as a fun activity to host a partner from out of town. It was a simple process to meet Denny at the dock. And the fun immediately began once we hopped in the boat. Throughout the ride, Denny shared invaluable context about each historical/ DC site we rode past, which made me fall in love with the city of DC even more! If you're looking for a laid-back and insightful experience exploring DC, Denny is your guy!
