I’m planning a 2-3 week European vacation as a graduation gift for myself in middle May/early June. I enjoy the historical aspects of Europe and would feel most safe with an escorted tour. That being said, I do not want to sign up for a tour with all elderly people or 18 year olds looking to get drunk. Any suggestions on a European tour for a single 35 year old female? Also, what is the difference between first-class and budget in escorted tours?

Kiley,
I have only ever been with a youth tour group, but when I went with them the guide talked a few times about how he had taken individual tours with older people, and I bet he would do it again on request. I don’t know how other tours are, but I had a great time on his.
At the very least, you could write to him and see what he has to say. Couldn’t hurt, anyway. (I hope that helps!)
