We've cruised with Tauck numerous times. We were scheduled for the Rhine Christmas Cruise in 2020, but because of COVID it was rescheduled to Dec 2021. We got a call two months ago saying our Dec 2021 Christmas Cruise was cancelled because they had contracted the boat out for another venture. We emailed them about it and never heard back, not even and apology. They said we could get our money back or schedule for 2022. Not good customer service.
