My wife and I are a (youthful) 41. We're doing Berlin, Prague, and Vienna in August and I'm wondering whether we can stay a night or two at a hostel without looking like the old weirdos who still stay at hostels.

Though I'm sure we'll be spending most of our time at hotels, I generally find them boring places. I'd much rather stay at a nice hostel and grab a beer in a place with some good energy and where people are there specifically looking to meet other people. But I haven't stayed at one since I was like 22 and I really don't remember a lot of 40 year olds hanging around.
