The Wyndham Grand Desert has a shuttle that will take you to Town Square Las Vegas every day. If you have never been here before and have limited time to shop, be sure to download the iPhone app prior to your visit. Super helpful for logically mapping out which stores you want to hit up.
I didn't download it until I arrived and was standing in the apple store getting some free Wi-Fi but it still helped.
This pedestrian plaza has a lot to offer. I wish I'd had more time there. And I'll definitely return.
