Thanks, Mac! I'll admit the screen name is left over from my high school theater days, but once a fanatic, always a fanatic, apparently.

The train to Philly is only about 2.5 hours, so it's really not a hardship, and the lost hours of sleep are nothing compared to Manhattan room rates.
Thanks for the suggestion about previous threads. Though a lot were theater specific, some had suggestions of hotels who might take bags that I'll have to explore (this one in particular:

I also found the Schwartz place when I was researching, but they close at 11 pm, which will be tough if not impossible. Unfortunately the Penn Station bag check and various others close even earlier. Maybe I'll just travel light.
