If you want prime rail side seating on the upper outside deck, you’ll need to get in line to board at least an hour earlier than your departure time. Another option for outdoor viewing, is to board, and go to the bottom level. Once the boat leaves pier they open the bow for standing.
Don’t pay extra for premium options. Not worth it!
The boat will be crowded. If you’re not seated on a rail, expect people to stand in front of you to get pictures.
The docent is difficult to hear at times.
It is VERY crowded, but a beautiful way to see the city.
