I took a trip on Go To Bus from Boston to Hartford. They provided the worst bus service I've ever had. Here is a summary of my experience with them:

1) In Boston, there was no sign to find the minivan at all where they'd mentioned there'd be a pick up, nor was there any notification of where to get the bus beyond “Christian Science Plaza.” I had to guess where the minivan was going to be waiting and barely caught it, even though I got there 15 minutes early as recommended.
2) The driver spoke on the phone a minimum of five times, not using a hands-free headset (not that this is acceptable). Talking on a cell phone while driving in Connecticut is ILLEGAL.
3) The driver sped the whole way, staying in the left lane, tailgating on the highway and cutting in and out of lanes to pass other vehicles. This was especially dangerous because there was heavy rain on Saturday morning, and at times, the visibility was very low (for example, the signs on the highway were barely visible) and the conditions were poor for driving.
4) The driver used no directionals when changing lanes and simply waited for a chance to move and took it.
5) After only one hour on the highway, the driver stopped to get gas. The trip was 1.5 hours in total; this should have been done ahead of time.

I emailed twice to complain, and after two weeks I received a response with instructions as to whom to call. When I called, the interaction I had with the "manager, " Jack, was as follows:

Jack never apologized for my terrifying experience, interrupted me when I gave explanations of what happened, and told me that the reason why the driver had been hired in the first place had been because he had "a driver's license and a clean record." I was told that he no longer drives for you and that he quit. When I asked "Jack" why they'd hired drivers like that without training, he argued with me. At the end of our conversation, Jack yelled into the phone, "Byyyeee" and hung up on me. Needless to say, I received no refund nor follow-up.

Please do not ever use this bus line. The savings is not worth it, and in this down economy, this kind of company is basically a predatory way for charlatans to scrape a little money off of people. BE FOREWARNED -- THIS COMPANY IS A SHAM.
