Lodging
Hostels
If you are looking for budget lodging (such as if you missed out on the event-provided hotel blocks or prefer a cheaper option), Hostels may be a possibility. To learn what a hostel is, see here.
HostelWorld is a website that helps find and book hostels and is recommended by Rick Steves, a well-known travel commentator who has a blog post where he provides european hostel tips.
For the uninitiated, hostels commonly have less private spaces than hotels. They often consist of shared dormitory style accommodations, but many also offer more private rooms for a higher price. The shared dormitories can be mixed or designated male/female only for visitor comfort, and many of them offer additional amenities like onsite food, tours, lockers to store/secure your bags, etc.
At least one Flock participant will be staying in a hostel for Flock 2025.
The main hostel that seems to be closest to the event venue is Onefam Arbes
Data Plans
Having an local SIM card (or eSIM if your phone supports it) can be massively helpful for getting around town (loading maps, messaging friends via Signal/iMessage, avoiding ludicrous roaming charges from your home carrier, paying for things online or confirming international card charges form your banking providers etc) when traveling.
Based on this techradar article, it seems like Airalo is a popular provider. They have plans that cover many different countries if you are traveling around via rail, or you can get cheaper single-country plans.
I have personally been using them for the past Month or so and have been quite happy with them as an eSIM provider. For about the same cost as a single day of international day pass under my regular carrier, I can get 2GB of data over a 15 day window across most of the European landmass.
Shameless plug: if you use my referral code ADRIAN88250 when you sign up or check out (or use this link: https://airalo.go.link/7MBLM), you can get USD $3.00 off

Sightseeing
This section is for those who are planning to stay a bit longer in Prague and would like to explore the city’s cultural and historic gems.
See also our Prague Recommendations for tips on local cafés, dining spots, and unique experiences off the tourist path.
Prague Castle
Prague Castle is a castle complex in Prague serving as the official residence and workplace of the president of the Czech Republic. Built in the 9th century, the castle has long served as the seat of power for kings of Bohemia, Holy Roman emperors, and presidents of Czechoslovakia. According to the Guinness Book of Records, Prague Castle is the largest ancient castle in the world, occupying an area of almost 70,000 square metres (750,000 square feet), at about 570 metres (1,870 feet) in length and an average of about 130 metres (430 feet) wide.
Charles Bridge
Charles Bridge is one of the most beautiful and photographed monuments in the world. It is guarded by thirty statues and sculptures of saints. They represent the great personalities of European and global history, each of whom somehow moved the world and changed it for the better. The magic of Charles Bridge stands out especially at night.
Old Town Square & Astronomical Clock
An icon of the Czech Republic, a national cultural heritage asset, a symbol of Prague's history and the oldest institution of Czech self-government. At the end of World War II, its underground served as the centre of the Prague Uprising against Nazism and the town hall was almost destroyed by shelling. Not even the bell from 1313 survived, and the altar of the Chapel of the Virgin Mary was also severely damaged. However, the people of Prague repaired their national treasure and today you too can enjoy the Old Town Astronomical Clock with the procession of the twelve apostles, the majesty of the state rooms, the tenderness of the Chapel of the Virgin Mary and the mysterious Romanesque-Gothic underground. Be sure to take a ride to the top of the Town Hall Tower, which offers a beautiful view of the whole of Prague. And don’t miss the hourly show at the Astronomical Clock.
Petřín Hill & Lookout Tower
A green escape right in the city, Petřín Hill offers walking paths, a rose garden, and a lookout tower resembling a small Eiffel Tower—with breathtaking views over Prague’s rooftops.
Vyšehrad
This lesser-known historic fortress offers peaceful views of the Vltava River, centuries-old architecture, and a picturesque cemetery where many famous Czech figures are buried.
Prague Zoo
Consistently ranked among the world’s top zoos, Prague Zoo houses more than 5,000 animals in beautifully designed habitats.
National Technical Museum
For lovers of science, engineering, and transport, this museum features everything from historic aircraft and vintage cars to old cameras and industrial tech. It's both educational and fun.
Other attractions
If you’re arriving early or staying longer, consider a boat cruise on the Vltava River, a visit to the Lennon Wall, the Franz Kafka Museum, or a stroll through Kampa Island for views of the Charles Bridge. You can also relax in Letná Park or explore the Baroque gardens of Wallenstein Palace for a peaceful escape within the city. For day trips beyond Prague, popular options include the medieval Karlštejn Castle, the spa town of Karlovy Vary, the brewery cities of Plzeň and České Budějovice, or the fairytale-like town of Český Krumlov.
