For those who do not yet have a passport, note that it usually takes at least 6 months to complete the process for obtaining one. You can fill out an application here!
If you have had a passport for a while, make sure to check the expiration date 😉
For Maine guests:
Logan International Airport in Boston is in our experience, the cheapest and easiest airport to fly out of. You can take a Concord Coach bus from Portland, ME directly to Logan for $61 roundtrip. Station parking is $5.50/day and it's secure. We highly recommend carpooling where possible to limit the amount of vehicles to be accounted for.
You can also fly out of Portland (PWM). While this option may be more convenient for some, flights from Portland tend to be pricier with more layovers.
If you plan to do a lot of sight-seeing while in Prague, the Prague Visitor Pass is a good value. A 48 Hr Pass is $100 and includes admission to more than 70 museums and attractions in Prague including Prague Castle, the Royal Gardens, the Klementinum, Jewish Quarter, and Old Town Hall / The Astronomical Clock.
The pass also includes unlimited public transportation for the active period! Your Pass serves as a public transport ticket for the metro, trams, buses, the Petřín funicular and ferries.
