Spring Open Campus Help

I’m thinking about attending the Spring Open Campus in April but it’s going to be really difficult for me to get to Wellesley from VA in an inexpensive way. Also, my dad HAS to come along because my mom won’t let me go by myself. To anyone who’s gone: can I get some tips on how to get there that doesn’t require me (because I’m the one paying for transportation, etc) to go completely broke? Also any tips on what hotel my dad should stay in/ if he even has to stay at all?

MegaBus. Get it far in advance and your fair might only be $1. There are 3 towns in VA that go to DC, then you can get the DC to Boston route, then ride the subway to as close as you can get and take a cab from there.
