Liberty travel is a real find if you're on a budget & need someone who knows how to get you the cheapest flights & lodgings. They won't hound you with luxury trips & 5-star hotels or stare at you funny when you ask them about youth hostels. I booked a few trips with them & they were superb at getting me the best deals & letting me know about student & other discounts, especially for train travel. Lots of Penn & Drexel students use them because they're in University City, but even if you don't live there, it's worth a trip just to check them out. Even though I mostly book trips online now, I'd still use them over any other agency b/c they really listen to what you're asking for, rather than try to sell you something for the commission.
