Booked a 1 hour tour. Was informed just beforehand that we were “upgraded” to a 2-hour tour and another group would be joining us. Well, we had dinner reservations and really weren’t interested in a 2-hour tour. And we never would have booked a non-private tour. We booked the private tour for a reason. I will never book through Viator again. They are awful. This is the 2nd time we were “double booked” for a private tour in just 7 days in Switzerland. Never again.
