ok, I seem to remember that the packet I got with my interview said that a cab ride from the train station to Hershey would cost about $15-25, which to me does not sound awful. I don't know exactly what Amtrak prices are, but I have ridden Amtrak one way to Baltimore from Boston for <$70 (nope, no student discount!). I seriously doubt that an Amtrak train ride from Philly to Harrisburg (about 1/2 the distance) round trip is going to cost more than $200, unless you travel at an off time like the Thanksgiving Holiday. On the other hand, "puddle jumper" flights that make the <15 minute flight from Philly to H-burg are more than likely going to be at limited times since it's such a short distance, and they are probably not going to be cheap. Also, you will probably be flying in a very small plane, which is a little scary, especially if you get snow (yay, just a few more hours til starts falling in Boston, can't wait!). You are also right to be cautious about the possibility of renting a car; I would guess that rental companies will not only charge more b/c you are <25, but b/c you are female and are therefore thought to be more likely to get into an accident by insurance companies. Also, driving in the snow is not cool unless you have done it before and can handle it. If you do rent a car, I'd suggest splitting the rental with someone interviewing around the same time you are, or bringing a friend/bf/parent along to help navigate. Greyhound bus is not bad or horribly expensive either. Good luck!
