I try to avoid shopping malls as much as possible, but this is my favorite one in town if I need to confront this necessary evil. It's best to avoid peak hours and days. It can get incredibly busy and hard to find parking. Fashion show is enormous and there are plenty of stores to choose from.
I usually stick to my favorite shops, so I am careful to park near these locations. The parking lot is color-coated and organized. There are lots of great stores and restaurants on the strip.
