Wonder if anyone can help answer this mlife versus promo code question I have. I have been to Vegas several times and have always stayed at MGM or The Hotel. I booked a promo code for The Hotel for end of Sep. It's an ok price but not as good as last year's $70 a night deal. Anyway, I am assuming I am a bit early and there will be another promo soon. Hoping to get the $70 deal. Anyway, I finally decided to sign up for Mlife. I don't gamble much at all, but figured I would give it a try this time since I seem to always end up at MGM properties. I am signed up but haven't even picked up my card yet. If I log in I see some offers already. The offer for The Hotel beats my promo price by about $70 total. Better price, but not as good as $70 a night. So can I call The Hotel and tell them I now have Mlife. Do they re-book under the Mlife program, or do I have to cancel, and book through Mlife online? What happens if I then get a promo code for $70 a night Do I have to cancel Mlife and rebook? Would you book through Mlife, or just wait it out for a promo code? Is there any advantage to booking through Mlife even if it is higher?? Points etc? Thanks for any help. Still new to this Mlife stuff.
