The Marina was added to the Disneyland Hotel in 1970 along with the Marina Tower. There were many adventures to be had including the use of Pedal Boats. Initially, the rental of these boats was free but upkeep, maintenance and replacement costs soon changed that.
One shot shows the entrance to Atari Adventure which I will cover in a later posting.
Trivia question for you: what was the proposed original name for the Marina Tower?
