We just returned from this tour and are so glad we went. The trip was fabulous, as was our TD Whitney. There were 25 in the Tauck group and 65 passengers in total on the Wind Star. Very impressed with the ship and the crew - we may not be able to be on a large ship again! Vaccination cards were checked for entry to museums and archeological sites, with limits on group size and number of visitors. Masks were required indoors except when eating/drinking and outdoors if social distancing could not be maintained, including on the ship. This just became our 'normal' and everyone willingly complied. It did not impact our ability to enjoy all aspects of the trip. We did not go to Ephesus which was a disappointment but we went to the island of Milos instead. This was a great time to see Greece without the crowds, especially in the more popular islands such as Santorini and Mykonos.
