Probably, if you valet.
But if it's very busy, you may be turned away even if you plan to valet. For example, on the weekends during Food & Wine Festival, the entrance guards often turn away all but guests actually staying at BWI or BWV. Usually, they direct those guest to the lot across the street, but there have been reports (on the Transportation Forum) that even that lot is being monitored this year during F&W.
Anyway, you should be OK if you valet.
