The EU's Entry/Exit System - the most significant change to European border crossing in a generation - is generating real anxiety among British passport holders, many of whom remain genuinely uncertain about what to expect when they arrive at Schengen borders in 2026. A question posted to r/solotravel ahead of a first solo trip to Copenhagen captures the wider confusion: "Does anyone have any experiences with this, and do they ask a lot of questions and ask for proof of accommodation now? I'll be staying with a friend so won't have hotel bookings."The short answer is: EES is real, it is running, and UK travelers need to understand what it does - but it is not the ordeal some feared. Here is what actually happens at EU entry points now, based on official EU documentation and traveler reports from across the Schengen zone.What EES does: The system digitally records when non-EU nationals - including British citizens post-Brexit - enter and exit the Schengen Area. Your biometric data, fingerprints and a facial photograph, are captured at first entry and stored for three years. Subsequent entries within that period draw on the stored biometric, making border crossings faster over time. The system tracks how many days you have spent in the Schengen Area against your 90-day-in-any-180-day allowance, replacing the old paper passport stamp system.What EES does not do: It does not require hotel booking proof as a condition of entry. Border officers have always had the right to ask where you are staying - that has not changed under EES - but providing a friend's address is entirely valid. The question travelers face is the same one they have always faced: can you demonstrate you have a place to stay and means to support yourself? A friend's address, their contact details, and reasonable funds satisfy that requirement.Processing times at busy crossings - Paris CDG, Amsterdam Schiphol, Frankfurt Airport - have seen longer queues as the biometric enrollment step adds time for first-time entries. UK travelers should factor an additional 20-30 minutes at major EU airports for the first EES registration, and arrive with appropriate buffer time for connections.The practical advice from experienced Schengen travelers: carry a complete address for where you are staying (even if it is a friend's flat), have your return or onward ticket accessible, and know your planned length of stay. Border officers are not hunting for gotchas - EES is primarily a tracking and overstay-prevention system, not an interrogation mechanism.For UK travelers visiting Denmark specifically: Copenhagen Airport runs relatively smoothly, and Danish border officers have a well-earned reputation for professionalism. Solo travelers with clear plans and reasonable documentation should expect a standard entry process, not an ordeal.
