We have a large group that will be staying in Alexandria and we would like to charter a bus from our hotel to Quantico for an event we will be attending. Can anyone recommend a charter bus company? Right now I don't have an exact number of people. The largest coach most of the companies seem to have is 55-61 passenger, so right now that's what I'm trying to price. I was just wondering if anyone had any positive (or negative) reviews.
