On an Interrail trip, you have three primary sleeping options: night trains, hostels/hotels, or "sleeper buses." Night trains are the classic Interrail experience; you can book a Seat (the cheapest, but hardest for sleep), a Couchette (a shared compartment with 4–6 padded bunks), or a Sleeper Cabin (private rooms for 1–3 people, sometimes with en-suite sinks or showers). These require a mandatory reservation fee, but they save you the cost of a hotel night while moving you to your next destination. Most modern Interrailers in 2026 opt for hostels or budget hotels near train stations to maximize comfort and local exploration; staying in "station-adjacent" accommodation is a popular strategy to avoid lugging heavy bags across a new city. For the adventurous, some high-end Interrail packages now include boutique stays or "Glamping" options in rural areas. Regardless of where you sleep, it is vital to book your night train berths at least several weeks in advance during the summer peak, as they are often the first part of the Interrail experience to sell out.
