I just hit six stays to max out the last promotion and earn three certificates. Now I've been offered the 50,000 for 25 nights promotion, which won't work for me at all. I'll stay a maximum of 18 nights (more likely 14 nights) in the promotion period. I'll try to change on Monday to the 3 certificates for 6 stays promo, otherwise I'll likely be staying elsewhere for 1Q 2013.
