Well, we got the cancellation notice today. Tauck is giving us our money back (I suppose to our credit card) and will give us travel vouchers for the insurance - we can apply that to a future trip.
We did our airfare outside of Tauck and will be able to transfer that to our next trip (non-Tauck).
So all is good. We're disappointed in missing the trip, but Tauck stepped up in this cancellation.
