all my travels have been with others.. i think it would be a good experiance to go solo and i'd really be open to go anywhere really but eh.. i dunno.. in my older age feel like i'd just be some crotchedy fuck who doesnt get along in hostels etc. lol
If you're considering Switzerland however, i'd say there probably isnt an easier place to get by, nor a safer place imo. Switzerland for the most part is exactly how you'd imagine..We took a fairly touristy route coming from Italy to the Interlaken Valley, which is surrounded by two of the largest peaks in switzerland, the Jungfrau and Schilthorn, it's very dependant on weather when you go up to their peaks, but man what an experiance if you hit it:
We only stayed in Interlaken and then in Bern before heading back to Paris, but it was definately enough to get a taste of the Swiss Culture and Life
Switzerland is expensive as fuckkkkk though.. between two of us we probably spent over $1000 CAD on train rides over two days, and the total amount of time on those trains was probably less than 6 hours
