I regularly shop at Costco and its usually one of five which ever is more convenient at the time. In all of my experience with Costco there is exactly one that has shitty parking, the rest are fine. That is if you have enough wrinkles in your brain to notice that in front of the store there 10 cars waiting for spot and parking a little bit in a back is easier.

I often see people cruising around still looking for parking while I already managed: to park, walk to the storefront, get myself a hot dog, eat my hot dog, grab a cart.
