Did you get the "friendly reminder" email from them this morning? I got an email "thank you for using National...below is your confirmation #...use it to view, cancel or modify the ressie... When I click on the link, it brings up my last name and a confirmation # (which I'm sure I cancelled anyway), but it says in red "Multiple coupons not supported by WEB" I did try one ressie using 2 EC coupons, so I assume that's what it is. It won't even let me view that ressie so I'm assuming they cancelled it, but I will call just to be sure. So for everyone who's hoping to use 2, 3 or 4 coupons, looks like the question has been answered!
