My friends and I are going inter railing and so will be staying in hostels across europe. One of the group will still be under 18 by the time we leave and several hostel sites have information saying that under 18 year olds have to book a private room as it is against the law to allow them to book a ned in a dorm. Is this rule strictly enforced in most places? And is it the same for the whole of the EU and europe? Thanks
No, there is no "Europe-wide rule". HI:
Do Age limits exist?
Youth Hostels are open to everyone. However age limits may apply for children in some places - check with the Hostel. Young people may be given priority when the hostel is nearly full.
Practices will vary from country to country and even hostel to hostel. For example, in Finland all ages are welcome, but at Eurohostel Helsinki under-18s travelling alone are required to present a letter from their parents with contact information. In your case, since the rest of you are "adults", you shouldn't need even this (although it's probably a good idea anyway).
