Was planning a bachelorette for one of my best friends in Boston, we had a group of 18 girls and needed to figure out a way to get around, the Bustonian it was! It was just this past weekend and I cannot say enough great things about it. The bus showed up and was in new condition (which I was a bit nervous about, you never know with some of these companies). We opted for the pink bus, it fit our group and the occasion perfectly. Has an ipod dock and great sound system. Cooler to  fit all your adult beverages and a dance floor.
Our driver was Don, he was both professional and helpful. You can pick spots on and off their recommended list, each driver has connections to door managers and promoters to help get in. As one spot we wanted to go to was way to packed, Don routed us to another place. Each time we were ready to leave, I would just text Don and he would be pulled up within about two minutes. The best part about the bus is that you skip all lines and have cover charges already covered (included in bus fee). You truly feel VIP traveling this way!
I definitely recommend this for a unique travel experience around Boston!
