I can only comment here that the guide booked for our trip, Nvard, was very professional (and would be worth a 5* review). She first contacted us a coupe of days before our planned trip to say that there had been heavy snow on a high pass on the road south towards Tatev. The day before she let us know that there was still a possibility that the trip would be cancelled She offered an alternative date but we already had plans for our stay in Yerevan. Later she sent a message saying we would be able to go ahead.
Unfortunately, on the day of our trip she had to cancel the trip to Tatev as it was not possible to clear drifting snow on another pass. This was disappointing but clearly outside Nvard's control. She had to consider our safety when making this decision.
Nvard reported the cancellation to Viator and told us thay would be in contact to arrange a full refund. Alas, not contact or refund to my card account (0* for Viator)
