Given my inexperience with Philly, I wonder if someone can suggest how much difference it makes for diners in the area of the convention center when a convention is in town. (I'm thinking everything from Rittenhouse square and a bit West to Chinatown and Old Town).
The convention in question is for academics in college language study (Dec. 27-30), and generally there are about 8,000-10,000 participants. Spread over a dozen or more hotels. It's not as wealthy a crowd as chemists or doctors, so the pressure on the high-end places will be more moderate than in those cases.
So, do local chowhounds find it to be a PITA when conventions are underway, requiring extra efforts at reservations, or instance? Or is it not so noticeable?
