for those with kids considering Balitcs, here is what we did in 2 Baltic ports with kids.
Stockholm: take the HO-HO that picks up right at the pier (get SEK for the Ho-Ho (Swedish $$) before you leave the US--they are not on the euro). Take the Ho-HO to downtown and walk around. You can go into the Palace, etc. but the BEST place was the Livrustkammaren. Founded in 1633, it is also Sweden's oldest museum. Set in the palace vaults, this armory isn't just about weapons but displays some of the world's most magnificent state coaches and coronation robes, even the costume worn by Gustav III at a fatal masked ball. (The king was assassinated at the 1792 ball, and the incident inspired Verdi to write his opera The Masked Ball.) They have a free kit that you can borrow for the kids--it is a box with a fake mouse and you find clues throughout the museum. My kids spent 2 hours doing this--super fun. They also have a good dress up place with princess/knights stuff, as well. We got the combo Ho-HO ticket and also took a boat tour. We did not have time to see the Viking ship (on the HO-HO bus/boat line). As an adult, I also really liked the above.
Tallin--easy to walk from pier to town and they have costumed persons selling nuts, sodas, etc.--very festive. Plus, you can do archery outside the fort with Red Riding Hood type costumed workers, fun to watch, even if you do no participate. Large square in center of town to get food, etc. Tallin looks like a storybook village from a fairy tale.
From an old
DCL, I got the idea to make "secret agent" dossiers with 5 things to find/do in each port--like try ____ dessert (famous for ____), climb the _____ tower, count how many steps at the _______. At the end, they got a little prize.
