I am traveling to DC in August as a Birthday surprise for my son. We are staying at the Holiday Inn central/White House location. The Peking here is $40 a night. I plan to arrive on a Saturday and park it till Thursday and take the public transit everywhere. Is there anywhere else cheaper to park for this amount of time without moving it unless I have too? $40 a day just seems insane if I’m not going in and out. HELP! Also, is this hotel a good location?
