Book in advance on www.hostels.com.
If its no written information that they take only 18+ and you have payed deposit, then its clear.

Try to plan ahead and contact the hostels you want to stay at, but I’ve seen plenty of Europeans under 18 who were staying at hostels so you should be able to find lots of places where you’ll be ok.

Is there any sort of law in each respective country as there is in the U.S. where you cannont book a hotel room unless you are 18? For instance I need a hostel to stay at in London, and when i look them up almost all say 18+. But if one forgets to include 18+ (as you say) how do I know I’m in the clear? I’m worried about this…..

In Scandinavia NO. About UK – suppose not.
But as far as I understand, some of them sell beer an the hostel and that demands a agelimit.

But call the hostel to be sure / then you sleap bether even the days before arrival

Just to clarify when you said Scandinavia-NO- were you referring to no laws prohibiting under 18’s to check a room?

Thanks fo your help though, I will call before and hopefully they can accommodate.

Another tip for “underage” travelers. Check the US State department website and call your airline and find out if they require any documentation to board the plane. Technically a minor can’t leave the country without the permission of both parents (including non-custodial parent). If you’re not traveling with both your parents you may need a “permission slip” with a notarized signature from each parent. You will probably never need to show this letter, but you don’t want to be denied boarding for your flight….
