If you are on a tour and one of the "top-tier" events on that itinerary gets canceled unexpectedly (such as due to weather, venue maintenance issue, road closure, etc.), how does Tauck handle that situation? I am talking about a special/unique activity that potentially is worth several hundred dollars per person, such as, a flight sightseeing tour, exclusive access after hours to a castle with a meal, etc. Does Tauck generally substitute another high-end activity (do they have back-up plans in place?) or does this tour portion just become free time? Do tour guests receive a partial refund or credit for the missed tour activity if a replacement activity is not provided? While some activities can be substituted more easily with a similar-type activity (such as replacing one winery or church with another), other tour activities are a one-of a kind highlight of that itinerary (such as Pompeii or Graceland). What are your experiences with last-minute changes of the special events/places?
