What travel companies are good during study abroad?

Lonelytraveler asked:

I’m studying abroad in Italy this fall. I want to go to other countries while I am there, but a lot of the groups I’ve been finding for “cheap student travel” seem questionable. Anyone have any good travel companies that were reliable, safe, and affordable? By safe (task lamps) and reliable, I mean I won’t be scammed.

How to travel cheap around Europe via Train?

Khairul F asked:

I’m planning to travel to Switzerland, Austria and Czech Rep this summer via train from UK. One of the cheapest options is to buy the Global Pass, which is only for European residents. However I’m not a European resident, which means that I need to find another cheap options to travel. Can anyone give any suggestions?
