Thanks, we've got both google traffic and waze handy. Also have the mapquest app and if I need to see a big electronic map I'll just hotspot my phone and open up my laptop.I'm rooting for you on this one. I've done the long drive a few times myself & I know how much you just want to get to the room and close your eyes & decompress. May you get a nice quiet room.
Oh a small aside, depending on when you're leaving for your trip you're going to want to look at traffic on I-95 South. About 20-30 miles south of DC it's a total grade a mongolian charlie foxtrot. You're looking at major back-ups because of 30 miles of construction. It's a mad house.
Alternate routes would include Highway-1 and ride that parallel to I-95. However, as always, consider google-traffic & waze reports to help determine when/if this is the right route for you.
The plan (which I'm sure will be insufficient) is to leave our home near the NJ/PA border around 3 on a Friday afternoon. Barring any emergency bathroom breaks (with a 6 year old and an in-process-of-getting-toilet-trained 2 year old, no guarantees there), we're gonna stop for dinner in Laurel MD around 5:30. While we eat, I'll see what's up on waze and other traffic sites. If both 95/495 and 295 are messed up, I'm going to backtrack a bit, feel my way down to 301 and take it until we get to RIchmond. I could be very wrong but I'm hoping a summer Friday in DC (during an election year), a lot of people will have already split the scene by the time we get there, and at least one route won't be too awful.
