Michael I was at the convention center just before the last snow storm. We arrived via Amtrak and h
a very easy taxi ride to Center City. The main roads were well cleared (very unlike DC!) and easy to travel. If you are staying close to the convention center there are tons of restaurnats in walking distance. The sidewalks still had a lot of snow but it didn't prevent us from going to dinner!
Make sure to save some time to go to the Reading Market, there is sooo much good stuff there.
Have a great trip!
