To be sure, a percentage of hostel customers do fit this description. While on recent hostelling stays in Europe, I was fortunate enough to make the acquaintance of interesting people ranging in age from their early twenties to late seventies. A small budget and an adventurous spirit. They offer a clean, safe lodging bargain that just can't be beat.
Bathrooms are communal and down the hall.
If, like me, you're loner, it may be less than desirable. However, the great price can make the trade-off a more than fair one. Hostelling is an excellent way for a family to stretch their travel dollars as the lodging is cheap and the on-site kitchen facilities usually available can even provide substantial food savings. Some hostels offer meals at a minimal price. Those in Europe almost always include breakfast with the cost of your room.
