Travel between Campus and Boston

Can some one advice how practical it is to travel from campus to Boston? I understand that PeterPan runs a shuttle bus, but how practical is it for students to use it for a day/weekend trip to hang out in the city rather than just as a means of transportation to catch a plane? Any help is appreciated.

On friday and sunday afternoons, peter pan runs the college express, which goes directly between Amherst and Boston.

I don’t think Peter Pan even goes to Logan, it goes into the city: http://peterpanbus.com/college-express/college-express-amherst-northampton-boston.pdf

And though the buses not on Fri-Sun aren’t called the “College Express”, the one my D takes form NYC usually goes straight from NYC to the 5 colleges. I assume the Boston is the same.

Unfortunately the express is only on Sundays and Fridays. On other days you have to transfer in Springfield.
