John,
Early start. I find it takes me about 6 - 7 hours to make it from here to Brooklyn or Manhattan. Getting out that early you shouldn't hit much traffic, and you're heading south, away from NYC so you should have a nice drive. Are you taking I-95, or going down the eastern shore?
Just checked the WVEC tower webcam. It's pointing straight at the pier. Hopefully they'll keep it there so I can see the ship before heading out on Saturday.
For anyone in NYC. The Maasdam is there until 4:45 this afternoon.
