<p>I second what spiraloflife says... plus odds are your host doesn't have a car. :)</p>
<p>If you want to go into Boston, you can take either the #1 MBTA bus across the river from 77 Mass Ave, or you can take one of the (free) MIT</a> shuttles, the Daytime Boston shuttle or SafeRide. </p>
<p>Or, realistically, you could walk. The weather should be nice, and Boston's only a quarter of a mile away.</p>
<p>I have a couple of links to popular Boston shopping areas in this</a> blog entry. Plus a map!</p>
<p>EDIT: And there will be approximately five zillion frat parties during CPW. You'll get a schedule when you check in. (Freaking out parents: they're dry parties!)</p>
