I'm looking at ways to get from the airport into town. Rick's book mentions a bus and a train, and mentions the cost of each, and that there's a machine for bus tickets, but not how to buy train tickets, or how pay for tickets. Will we be able to use credit or debit cards?
I was there the first two weeks of April - Gdansk => Warsaw => Krakow [on my own]. In Gdansk I stayed at Hotel Admiral - they told me that they would be hosting RS tours - great breakfast buffet.
Here is a link which describes the various options for getting from the airport: https://exploregdansk.info/transportation/getting-from-gdansk-airport-to-city-centre/
I was planning on using public transportation for the trip, and I wanted to get started right away, so I took the train from the Gdansk airport to Gdansk Glowny. If you follow the red line out of the airport [see the article] it will lead you to the train platforms, which are just outside the terminal. There is a ticket machine [takes credit cards] - I had a bit of trouble with it, even with English selected, until I used "Dworzec Glowny" as the destination. While my ticket indicated direct to Dworzec Glowny, and I got on the train that I thought was through to there, it was actually a train that terminated at Gdansk Wrzeszcz. Once I figured out that I was at the end of the line, I changed platforms and got on the next train to Gdansk Glowny/Dworzec Glowny [just keep in mind that in Poland, the initial reference is always to Platform, not track. You might inquire at the TI at the airport [after baggage claim] regarding the fine points of using the train. It's actually easier than it sounds, even with the transfer.
At the train station, I then planned to take Bus 100 to Fish Market/Targ Rybny, which is the stop half a block from the Admiral [also the Hilton]. This is an electric minibus, as it follows streets through the historic core that are too narrow for conventional buses. It took a while to find Stop 14 outside the train station - I learned that there is a poster inside the bus shelter that indicates which stop it is, and which buses it serves - there are a number of stops right outside the station. The stops on the station side of the road are for southbound buses, including 100.
The 210 bus from the airport is another option, and perhaps more direct, if you want to save money.
You can use Directions in Google Maps to look at various itineraries in advance - just set your departure time to the approximate time your flight arrives.
Bolt: I had read that Bolt was reliable and popular in Poland, so I downloaded the Bolt app to the phone. To register the account, it requires a validation code which they e-mail to you - I wasn't able to receive it until I reached Poland. While I had it ready, I never had a need to use a taxi. I also had the FreeNow app - I saw slightly more FreeNow cabs than Bolt over the two weeks.
Jakdojade app: This is useful for both buying local bus/tram tickets, but also as a route planner for trips using public transportation. You have to load the Jakdojade wallet with cash - I started with 25PLN. For Warsaw and Krakow I purchased 72-hour tickets from a machine upon arrival in each city, but there is less need for public transport in Gdansk, so paying for fares on the app made more sense. And I did always see terminals on the vehicle for buying tickets - and never saw a fare inspector.
