Heading to DC next month for a week. I'll be checking out of the hotel on Sat. morning, but my flight back isn't until about 5:30pm. Was hoping to use the extra day to spend some time at the Air & Space Museum (haven't been there in a few years), but I have no idea what to do with my luggage. I'm not renting a car, so I have to stash it somewhere. Any chance the hotel would hold it for me for the day?
