I have posted a series of trip reports on our trip to the Baltic States in August 2017. There were separate threads on Tallinn, Riga, Riga-to-Vilnius, and Vilnius. This thread is a collection of notes about our practices while traveling. There are few points specific to the Baltics, but most apply to any trip we take. I hope it gives you some ideas.
Language
The languages in the three Baltic countries are very different from English and from one another. Estonian is more like Finnish, while Lithuanian is more like Polish. I don’t have a good comparison for Latvian—logically, it would be more like Russian. They differ in sentence structure, gender, suffixes, and the use (or not) of definite and indefinite articles. If you are an English speaker, you won’t find many cognates, except for recent borrowings. Fortunately, English is the second language for many people (sometimes, third, after Russian), at least in the capitals. We did run into a few people who knew the words for prices but not much else. Our greatest difficulty was in an Italian restaurant! Out on the street, it’s best to memorize the series of letters in the names you are looking for. You can mentally make up whatever pronunciation that helps you recognize them.
Money
All three countries are in the Euro zone, which simplifies exchange. We always keep a cash reserve of $200 each in U.S. currency, but we’ve never needed to use it. We rely on ATMs for cash in Euros. On this trip, we visited ATMs only twice: upon arriving and in Riga (where I lost my card). We came home with a few Euros left over (to be spent on the next trip).
Most of our purchases were with a credit card. We ran into few vendors that did not take it. Indeed, we had trouble spending the 50 Euro notes that came in the mix provided by the ATMs. Most sellers didn’t want them, because they couldn’t make change.
We have not paid attention to getting the best exchange rate or avoiding fees. We weren’t on a tight budget, and that was a complication we could afford to ignore.
Transportation and Navigation
We prefer to use public transportation as much as possible. Our preferred method of getting around is walking. We walk 10 miles or more per day. For longer distances, our preferences are: rail, bus, taxi, and (way down there) driving ourselves. We haven’t driven on vacation in about ten years. We don’t even consider Uber or similar services and have never learned how to use them.
Our big exception to public transportation on this trip was the taxi tour from Riga to Vilnius. We did that because there was no other practical way to visit Žagarė. (It had the bonus of allowing us to visit Rundale and Tērvete.) We also made a similar exception in the taxi ride to the airport on the way home.
We navigate by means of paper maps while walking around. We start with the ones in the guidebooks. Those are good enough to get us to the Tourist Information office, where we can usually get a better one. Paper maps allow us to see more of the area at once, compared with the view on a phone. We also see more of our surroundings, because we’re not walking around looking at a screen. Maybe we get lost more often—but that is part of the adventure.
