1. Krakow: Pinball Museum Ticket
Take a trip back in time and hit some balls around in the Krakow Pinball Museum. A once ubiquitous feature of the 20th century, the days of pinball machines in every hotel lobby, bar, or arcade are long gone. Featuring 30 machines elegantly restored to their former glory, enjoy a retro throwback, all the while learning the history of pinball. Once you enter the museum, you’re free to play all the machines on offer — without paying anything for the machines outside of your entrance ticket. While you’re at it, have a drink at the lounge bar and relax.
