I don't know about that promotion having much impact, but the S CA 2fer sure will, especially on the last day the tickets can be used at DCA. Last year they had to send people over to DL because DCA was too full.
I just read on another site that this year, they're allowing the second day on that pass to be used thirty days after purchase? first use? Something like that. SPECIFICALLY to avoid overcrowding of DCA.
IOW, if someone comes in on April 26th and buys a 2fer, they have until MAY 26TH to use it up.
Okay, so maybe I need to rethink our April 24-28th trip. What is the second week of May like crowd wise maybe May 8-12th
