We're thrilled to have scored a White House tour for next week, but I'm wondering if anyone knows of any public lockers in the area where we might store our stuff during the tour. Perhaps the metro station? Nothing is allowed in and we are coming from our hotel in Vienna for an 8am tour (so suggestions would need to be something that opens early). We'd like to visit to spend the rest of our day visiting other things, but with two kids, we usually travel with a backpack full of snacks, camera, etc. Would it be worth it to try to drive in and park at that early hour so that we can store stuff in our car?
