In an effort to get off our feet, and see this beautiful city from a different perspective, we took the 60 minute tour.
I understand their limitations because the current was quite strong (they have had an unusually wet year)....so we looped around the central harbor area. I also realized as a Californian, I have some serious *water envy* .....and missed strong currents in rivers.
We did not eat on-board, but sat in a shaded part of the upper outside deck. Relaxing and informative, this is what I expected.
