Transportation for Semi- Boston
 

Hey guys!

I'm planning my sorority's semi formal in November and I was wondering if anyone could suggest some decent reliable transportation services for getting between Waltham and Boston?
There will be around 120 people going, so we'll probably need a bus, I've heard that its cheaper to do two trips, is this true?

Thanks!

Why not get two or three school buses? I doubt people would want to go staggered.
