I found the Viator tours to be fun and they offered some unique things. For the most part the tours were dependable and well organized. The dinners with hosts in cities. Red a little work. They need to ask more questions so they can fit you with the correct host/hostess and the correct menu so that a person can have the complete experience they are expecting. In each of my experiences the hosts/hostesses were wonderful but the food was disappointing and even after I had booked and paid for the dinners I had to keep following up to get the address, etc. But the dinners are good idea and I'm sure they will work out the kinks. All in all I found Viator's tours well worth the money.
