During President's Week 06, DL was open from 9-8 and DCA was open from 10-10. However, when we were there, we entered the Matterhorn line at 7:45, got off the ride after 8, but then still rode BLAB AND Indy before we left at around 9.
The hours for the rest of February would probably be the normal off season 10-6/7? and DCA 10-10
