Yeah that's fair enough I guess. I've been travelling all over Europe but never been outside it - I went interrailing last summer with my now ex-girlfriend, probably the best thing I've ever done. If you've got the money I'd totally recommend that.
Out of the places I went, I'd probably recommend Norway if you're a solo traveller. It's suuuuuuuuper expensive, but if you stay in hostels then you can save a load of money and also meet new people. I stayed in Bergen for 2 nights in the Intermission Hostel, and as I turned up there was a group of people who were all solo travellers that had just met each other, and they all bought some camping gear and went to the top of one of the mountains in Bergen and camped up there for the night - I was so jealous because it sounded awesome! There's plenty of hiking related things to do all over Norway which is great for a solo traveller.
If you have questions about any of these countries then I'm more than happy to answer them: Finland, Sweden, Norway, Denmark, Germany, Czech Republic, Hungary, Slovenia, Italy, Austria, The Netherlands, France, Spain, Gibraltar.
I visited all of those on my trip except Spain and Gibraltar. Also I went to one or two cities in each country so I may not be able to answer very specific questions, plus some countries I know a lot more about anyway.
