Philly is nice. I go there several times a year, and there's lots to see and do.

The only thing I would suggest is a hotel closer to what they call "Center City". Penn's Landing is a bit out of the way and not really walking distance to any of the other attractions.

We have at least two Philadelphia members that I can think of: Johnny Ola and Big Daddy Don. And Beth lives in Baltimore, only about 2-3 hours away.
