Visiting in June

Tere and Sveiki!

I will be ending a 20 day trip to Scandinavia at the end of June, and have 10 days to visit the Baltic countries. We (67M, 60F) plan to ferry from Helsinki to Tallinn, spend a couple of days there, train to Riga for a couple of days, then to Vilnius, then to Klaipeda for a ferry to Copenhagen for the trip home. Does this seem reasonable? Are trains easy to get or do I need to make reservations? How about hotels during that time (late June-early July) - should I make reservations now? Any regional chains that are good?

Also, what’s your comfort level with the Ukraine war? Do you have concerns? I know the Baltics are part of NATO, so there are protections as part of that.

I’ve wanted to travel in the Baltics for years, and I’ve very excited for the opportunity. Any suggestions or advice welcome. Thanks!
