This is a great Costco. My only complaint is when they stop buying something I've come to depend on.
It's an extremely busy location, particularly during weekends, so sometimes your best bet for parking is to park near the other stores. Less frustration. Best to go during the day on a weekday.
Now that they have the gas station, it's busy to the point of requiring traffic directors during high gas demand (I.e., high prices elsewhere). Note that you must have a member card to pump gas.
