Was NOT happy with Viator, when I booked the Montreal Tower and Biodome Tour I upgraded and added the Botanical Pkg. Upon arrival they said Viator was NOT an authorized dealer to sell the Botanical and I had to speak to numerous supervisors to get it resolved...given that i had PAID for this pkg and it was on my reciept confirmation! well my demands were honored after 45min debate and it was a great experience for our family. Kids (7,10) enjoyed Biodome which was an Aquarium center, they enjoyed the elevator ride up over the city at the tower and the Botanical Garden was a true treat and pleasure to see and visit.
