Where are the truck loading docks/area located and can you service a 53 ft. Trailer with road sleeper tractor

I think you should call the hotel directly and ask to speak with their maintenance department. I'm sure there are zoning restrictions about loading and unloading trucks, given the Center City location of the hotel

Oversized vehicles such as 10+ passenger vans; Dually trucks; exceeding 6 feet, 6 inches in height; roof top racks; trailers will not be accepted by valet due to parking limitations in the garage. Please call the hotel for more specific information on your vehicle.

PA Convention maintains a staging yard at 8th and Callowhill.

Yes. I was thinking the same. Thanks
