i would have agreed w/those that said "save the money" 'til our aug/sept vacation and our flight arrived on time, i ran to the alamo line while dh/kids got the luggage... 50+ people ahead of me, and NO ONE on the national line... forget the good rate, i went for the quick service... imo it was worth getting to the world an hour or two earlier... heck, if i wanted to save money and waste time, i would have used mears!
