有关于灰狗及其他大巴的行李问题

我暑假去大西洋城打工，从纽约去大西洋城的车有灰狗，mega, 但是我应该有两件大行李，大巴规定只能带一件，要不然好像要多买一张票？这个怎么办呢？有没有遇到这种情况 的驴友告知一下？

下面是mega的规定：

If you wish to take an extra piece of luggage, you should purchase an additional travel ticket in advance of travel. This guarantees your luggage space on the bus, which is limited. Customers presenting additional pieces of luggage without an additional passenger reservation for such at New York, Philadelphia, Baltimore, Washington DC, Boston, Atlanta and all Texas cities will be requested to pay the full walk-up fare for the carriage of additional pieces of luggage. The carriage of additional luggage is at the discretion of the operator or dispatcher and usually dependent on the available space once all legs of the bus journey have been considered. In the interests of safety and the prevention of injury to employees and associates, no pieces of luggage over 50 pounds in weight are allowed - regardless of whether additional reservations have been purchased or not.
