If I could give a zero star to Viator I would. Buyers be aware. Viator is an irresponsible company to do business with. Booked a one day tour in Costa Rica through their web site. Fully paid. Requested their local touring company to contact me to finalize transportation details. Never heard back from the local touring company. Next day contacted Viator. I was instructed to go to a specific hotel in San Jose, and was given confirmation that Viator had confirmed hotel pickup at 5:00AM. Since the hotel was far from my residence, decided to book a room at the hotel and drove 2hrs to get to the hotel. Upon my arrival to the hotel, I reached out to the local touring company just to confirm that I am there and expect to be picked up the following morning at 5:00 AM. No response. At 8:00PM, contacted Viator again to let them know that I had still not heard confirmation from the local touring company. Viator rep tried several times to get a hold of the local touring company as well without any success. Viator rep told me to go to the lobby area of the hotel at 5:00AM, and if no one shows up to call Viator again. Woke up early, went to the lobby area at 5:00AM, no signs of transportation. Called Viator again and was told to wait in the lobby are till 6:00AM and call them back if no local transportation did not show up. Called Viator at 6:30AM, and they still can't get a hold of the local touring company. After being issues a refund, the agent has the audacity to try to sell me another day tour. No thank you. Complete waste of my time and extra money in trying to arrange a meaningful tour while vacationing in Costa Rica. Do yourself a favor, do not by any means do business with Viator. They are irresponsible, only interested in money, and they will leave you more frustrated and angry than is worth.
