Viator’s communication about the departure time was inaccurate. We were on time for a 2:00 departure, but waited for another party to arrive after 2:30. Young people fell asleep, older were more engaged. Tour guide nice but inaccessible for the under 50 crowd. Viator said there would be 3 stops, only took one. Bus was stuffy, even with A/C going. Alison spoke continuously, interesting information, but some quiet moments would have been nice. An expensive tour for what it was. Our 24 year old daughter & friend fell asleep.
