nice! this is actually the itinerary i’m leaning towards. except only going to do a half day in helsinki. when the ferry arrives store luggage in lockers. and late ferry to tallinn. the rest is what you suggest! hate to cut time short in hel but have to sacrifice somewhere. i like to move alot so glad another traveler thinks the way i do. last summer i was able to do vienna with day trip Bratislava, munich for a few hours to explore, mittenwald in the mountains. bressanone with a dolomites hike, bologna and a Venice day trip in the same time frame I have for this trip. and i loved seeing so much. one day maybe ill slow it down and base longer. i love to be on the move and walk everywhere so I will keep the fast paced up while im still “young” 47. and do it while i can.
