Excellent tour guide. Modern coach or bus. A lot of pretty sites. This city you were allowed to return to the ship on your own.
Enjoyed the sites we visited, but the store they took you to shop at was set up for only cruise line passengers and items could only be purchased with dollars or euros.
It was a small boat with limited seating on top deck and if you seat in the interior of the boat it was very hot and no way to open windows. And no snack available.
As this was a tender port there was a bit of confusion getting off the boat on which tender to get on escorted or not escorted. But all the sites we visited were pretty and worthwhile. Was allowed to return to ship on your own.
Tour guide was knowledgeable of Tallinn and her country.
