If there is truly nowhere to sleep, a 24-hour venue is only a one-night fallback; try a relief station first
An accessible airport or station waiting area may get you through one night with a toilet and a charging point, but no official data establish that this is safe. Keep valuables close, decline food or drinks from strangers, and avoid isolated corners. Do not sleep under bridges, beside rivers, or on construction sites. A relief station provides food and shelter free of charge and should be the first option.
What it takes
Airport and railway-station waiting areas may cost nothing to use where access is permitted. Fast-food restaurants and internet cafés usually require a purchase. Sleep is poor and belongings may be stolen; you may feel unable to relax all night.
What you may gain
A suitable venue may provide somewhere to spend the night, use a toilet, and charge a phone. There are no official numerical estimates of benefit.
Context & considerations
Safety risks are real. Keep belongings on your person, do not accept drinks or food from strangers, and avoid secluded areas. Sleeping under bridges, beside rivers, or on building sites at night is unsafe, and exposure in extreme weather can be fatal. Try a relief station first for free food and shelter. Some venues clear their premises overnight; do not get into a confrontation with security staff.
