Thanks to everyone for the ideas. I booked a hotel for Boston, about 8-10 miles out from downtown. The hotel shuttle will take us to the train station to go downtown. The lady at the hotel was VERY helpful and suggested a 5-6am start time to get in the main area!!!!! She works security at the Hatch Shell on the 4th (2nd job) and offered to call me back with more information!
Now on to the DC hotel. And the paperwork to visit the White House. Wish me luck!
