Oh really? Hmm...I guess I'll figure something out then. The place we're staying has a fridge and freezer in the basement we can use but that makes me kinda nervous. I don't really trust people that much that I'd wanna leave stuff in there. But I'll see when I get there, I guess.
Where are you staying? In VA, I assume?
Anyway, since you're just talking about lunch, you can always just get individual servings of stuff like fruit, yogurt, soup, or sandwiches. You will no doubt have access to a microwave to heat individual servings of things.
Maybe there will be access to a fridge at the Pentagon that the office you are based in can use. We have a fridge at work that we can leave stuff in and then make sandwiches, toast even a microwave if we want to heat something up.
