I received the solicitation above today. The code is REG. As far as I can tell, there is no promotion and REG stands for Regular rate. The terms and conditions include:
Terms and Conditions
Valid seven days a week through 12/31/14. Limited number of rooms are available for this promotion. Tax is additional. Offer does not apply to groups of 10 or more rooms. Offer cannot be combined with any other promotions. Blackout dates may apply. Advance reservations required. Other restrictions apply. Rates are per room, per night and based on availability at the time of reservations.
But......the joke must be on me. Why call it a promo and have terms and conditions if it's the same 'ole rate?
