Avoid!!! We booked and paid for this tour more than month before, the other family who was waiting for this trip as well booked it many months ago. Day before trip we got message with tickets with date, time and meeting point. We and other travellers arrived to meeting point and 30 minutes after departure time we decided to ring this Day tour Sicily. One man answered the phone and told me he has nothing to do with travel company, when I rang him again, he told me that tour is tomorrow not today, and that was a total lies - on our bookings and tickets was today's date. He offered us to change for tomorrow, but we was sure those are another lies. Our day was ruined and this is huge minus for Viator as well.
