Beg to differ, Slippahs. That d****d parking lot at Costco Iwilei appears to have been designed by the same idiots who laid out the street parking spaces in Honolulu. In other words, it's a nightmare. I'll never go back if I can help it.
Even though it's smaller and further away, I much prefer the Costco in Hawaii Kai. It's not quite as busy since they opened Iwilei, which makes it all the more pleasant (on a relative scale, or course). I've never been unable to find parking, even on a weekend.
