Pros: I have next to an Amtrak employee who showed me where to go to get my connecting train. Cons: It was unclear what gate to use for my train from Philadelphia to Harrisburg. The gate was above a doorway, so I thought I was to go through that doorway, but instead I was to go downstairs and I only knew that because someone told me to line up to get gate 7 "downstairs.".
