There will be an afternoon rush getting out of Baltimore heading south down I-95, but its not bad. However, the I-495 Beltway around DC and I-95 South of DC is horrible on the afternoon rush hour.

There will be some traffic on I-70 West out of Baltimore for the afternoon rush hour, but not too bad. Baltimore's afternoon rush hour starts a little later than DC's (business and medical town vs. a gov't town).

I-95 is a very delicate road. One little fender bender, and your in a backup for 10-20 miles. I-81 is just as delicate, but much less likely to happen.

I use "pc miler practical open" for commercial reasons and is pretty close on the miles. If you run up 81 vs 65-85-95 etc its apprx 100 miles more. Stay on the flat road on the way back and as Brian said above try and time your route to avoid rush hour.
An alternative around DC is rte 301. A few lights and posted speed limits but not too bad.
