Anyone have any experience with using these app's while at the sportsbooks in Vegas? I'm heading out tomorrow and just read an article about them, and how you can avoid the lines, by downloading the app for the specific sportsbook, signing up and funding an account with one of the cashiers and then make all your wagers from your phone, and then withdraw your winnings right there at the sportsbook. Seems like a pretty good way to bet games when any place I go will be wall to wall people and 100 people deep lines.
