I have a night at almost "any" Sheraton expiring in my account on Dec. 13th. Came from SPG promo stay 5 nights get one free. Unfortunately this promo had a VERY SHORT time to redeem, only 3 months which I find below standard. Also my SNA are expiring the end of this year... How about some extension here from SPG? I would really appreciate it after all the recent news re. Starwood and Marriott.
