We've been keeping you posted about all the deals to be had in Las Vegas: $99 weekend rates at Trump International Hotel and Tower, $65 rooms at the swanky M resort... And the hotel price war continues. Luxury hotels continue to slash their rates, with Steve Wynn leading the pack, of course, announcing additional discounts of 25 percent (plus a $100 spending credit) for bookings made 45 days in advance at Wynn Las Vegas and the Encore. And yes, you can use that spending credit on tickets to see the Garth Brooks show, "currently the hottest entertainment option on The Strip,"-- to quote Arthur Frommer. [Map]
