My $208 last night is now $241. (mid SUV June 28-July 5, Alamo Costco). Will keep checking!
ALSO: I book thru the Costco site, and they DO ask for your Costco ID #. It is nice to do it thru their site because it is easy to find your paperwork, and easy to cancel prior reservations. Clearly they intend the discounts to be only for Costco members, but there seems to be little enforcement of this. Irks us actual members slightly, but I used to use random codes I found on this board all the time, too, confession time, haha. So not my concern.
I also do go into the alamo site to print the paperwork to Skip the Counter.
