If you are planning on staying at the Wynn or Encore you can get a $100 resort credit for booking at least a 2 night stay. I have seen rates staring at $149 and up.
The coupon code is: RESCRDT
Go to Wynn Las Vegas Reservation Page, that will pull up a date calendar and other info, make sure to enter to coupon code, and then search dates.
Remember to read the terms and conditions, especially:
RESORTCREDIT included in this offer is valid toward items charged to your room at Wynn Las Vegas and Encore excluding room rate, retail items, casino play, Garth Brooks tickets, gratuities and taxes. Unused RESORTCREDIT will not be refunded and has no cash value.
