Lose the clunky guidebook and let Mate give you on-the-go hotel, show, and club reviews, restaurant menus/reservation booking/late night openness, plus daily and weekly poker games & tournament times/locations/entry info. It'll also answer common traveler queries like "Why is Bellagio's buffet line so long?", "How much should I tip??", and "What is, and how does the $20 hotel-check-in upgrade trick work?", and no, it's not that kind of trick. That costs $40.
