It's getting warmer in Las Vegas, and the hotels are starting to promote their summertime rates now, so if you book early you can still get a great deal before the thermometer climbs to 100 degrees in the shade.
The Wynn has a promotion for stays from May 25 through September 7, 2009 starting at only $109 a night if you use code MJJAS15 when you book. With this deal, you must book at least 2 nights to get a $50 resort credit (for room charges), and they will upgrade you to a suite at the new Encore (if available) at no extra cost! If you stay four nights or more, you also get a $25 slot credit. If you can only get away during the week-end, it's still a bargain at $159 per night.
I checked on several of the big internet sites for their rates at the Wynn and Encore during this time and they range from $239 to $259 per night with their "discounted" rates, so with this deal you get two nights for the price of one, and that's not even counting the resort credit or the upgrade value.
Better make a reservation as soon as possible, these rates and this upgrade won't be available for long.
