Mousesavers.com has a phone number for "preferred ticketing" that you can call if you have an Alamo car rental ressie. It's a 3 day hopper with one plus option...$179-ish/adult. $135-ish/kids. They DID ask for the ressie# both times I called (the first time just to see if it was for real). Ordered & paid on the phone, then picked up at will-call window (they would've mailed them to me, but I ordered only 1 week before our trip). By the way, when I called the regular number (which is the only number provided at Alamo's site), the CM had no idea what I was talking about. Thanks to Mary at Mousesavers for that preferred ticketing phone number!!
