I actually got boarding pass from online check in at to print at home. But I found a place called "Hostelfly" near T2 so walked there and slept for 5-6h insted. If you do HBO and have a short night transfer at T2 or T2, its great to have a (dorm) bed and shower for €28. Felt safe, clean and quiet. With large bags, it wont work with there lockers and you need to take a taxi to go there. Walking were just 10-15 min on sidewalks and a pedestrian bridge
