This could have been an outstanding experience as the evening was lovely and the sights, not only
historic, but beautiful from a different perspective other than a street view.
It began with being refused boarding because although they sell electronic tickets online for this boat ride, they don't accept them. And there was no posting nor indication that they wouldn't take e-tickets. After waiting in a long line to board 5 minutes prior to departure, I had to leave my husband (who was walking with a cane due to a recent injury), find and run up to the ticket office (where I had never been), wait for them to record my name on a list, be given two paper tickets, and then return to the boat where I was promptly told by the rather rude boat man that the topside was full. We did go topside and find two seats after we had to force our way through a rather large group who were blocking the top of the stairs (and with a dog who was not a service animal).
My poor husband also had a terrible cold. I went downstairs to buy a soda and was told by the same rude guy that he wouldn't break my $20 bill as they refused to take anything less than small bills. They had plenty of small bills and could have changed the $20. Unfortunately, my husband continued to cough without relief as I couldn't buy a water or soda. Sorry that ATMs don't dispense $1 and $5 bills.
Midpoint through the tour, the gentleman on the boat told everyone to be quiet as he was delivering his tour diatribe. We were all quite able to hear him as he was on a PA system which was adequately loud. I thought this rather odd and somewhat rude.
When the tour concluded, the tip bucket was present. I obviously didn't have anything smaller than a $20...so no tip.
