This bustling convention hotel—the biggest in Pennsylvania—fills an entire city block. It has so many corridors that even the staff sometimes gets lost. For an intrinsically impersonal type of place, the Marriott tries hard to meet special needs; it also offers some of the lowest rates in its price category. The softly lit lobby has comfortable seating areas with a sushi bar and a Starbucks steps away. The more than 1,400 guest rooms are brightly decorated. You can request, at no additional cost, one of the 250 "rooms that work," with adjustable desks and extra lighting and outlets. A Kinko's and FedEx is also on the premises. The hotel restaurant, 13, serves contemporary American food. If you're driving, you may want to park in a public parking lot, as the hotel charges upwards of $45 (including tax) a night.
