Drove 4 hours from Liberia to San Jose, Costa Rica. The tour was cancelled a day before. We rebooked for the next day. It was cancelled AGAIN. They book as many people as they can and then cancel the excess, as they claim they are operating at 50% capacity due to COVID. This pandemic has been going on for a year. They KNOW what the max occupancy of the tours are. They just want to sucker as much money out of as many people they can and then cancel when they meet their agenda. Completely unprofessional and unacceptable. Do NOT book with Viator. Will be posting this review to as many sites as possible as a ‘buyer beware’.
