I've never made it from Philly to Baltimore by car in less than 2 hours (without stopping). Getting through CT and New York is traffic heavy. From Philly to Boston with no traffic and 2 25 minute "rest stops", is about 6 - 6 1/2 hours. So total drive is realistically 8-9 hours. And you aren't seeing anything. The big food in Boaton is SEAFOOD and BALTIMORE is on the HARBOR so plenty of Seafood there! Just saying...
It's 407 miles and Google Directions say that from the Hyatt in Boston to the Raddison in Baktimore is 6 hours 48 minutes (if you leave NOW 8:50 PM and hit no traffic).

By all means go to Philadelphia, which is a fine town. However, Boston to Baltimore should not be a ten hour drive unless something goes very wrong. Boston to New York should only be about 4 hours, and New York to Baltimore should be about 3 hours. YMMV, but I've driven both of these routes dozens of times.
If you do decide on Boston, let me know and I'll get you some seafood recommendations.
