Viator does not have your back I purchased 3 tickets through Viator 6 months ago for a helicopter trip provided by Blue Hawaiian. I was later informed I would need to pay an additional fee of $170 because of my weight. I requested the fee be waived, which blue hawaiian agreed to. On the day of the flight they demanded the fee anyways. I refused and they would not refund me. Viator claims they are there for the consumer, but they sided with Blue Hawaiian in the dispute, I do not believe they took my case seriously. As blue hawaiian broke our agreement the day of the flight. Don't trust Viator to do the right thing.
