Here's what you need to know that isn't about shopping:
1. There is free wireless to be found in Vegas. We learned the hard way (by checking everywhere we went). There is a Starbucks with a T Mobile Hot Spot in Fashion Mall. If you use T Mobile, you're welcome. If you don't, go to the Coffee Bean in Planet Hollywood's Miracle Mile.
2. Right across the corridor from Starbucks is a half price ticket outlet that gives half price coupons for dinners and shows. We tried them for both and saved bank- pretty nice for just finding the place serendipitously.
