A BIG mess - After booking and prepaying 2 months ago and receiving confirmation from viator the day before i started messaging the operator as soon as my cruise ship docked at 6:40 for no answer. We all disembarked and went out in the hot sun thinking that our pricey private tour will be waiting. But no one was there for us. I messaged again at 8 and 8:15 and 8:30 and when i called viator (paid call back to the us) and held online they were able to send him an email and sent me a phone number direct to the operator in napoli. They wouldnt answer and later texted me saying they had no reservation for me. Around 9 when i sent them screenshot confirmation they alleged this was flagged for cancellation! Finally they proposed i wait few minutes to find a solution. Half hour later they asked me to wait again and after wasting about 3 hours of my day they cancelled on me. I had to take my wife and two children in the burning sun to the ship terminal and could not leave the port until 10:30 for a 3 hour day! I am hoping viator drops tjis operator and i am waiting for a full refund and extra crefit fory hardship. After all i wont be in Naples again and they wasted my chances at having a nice day. Stay away.
