This may be a no frills, simple way for Mlife to build their database through the Facebook pages of MGM Resorts' hotels. We're less concerned with that and are happy take the points and hope for the best!
You can sign-up for the promotion on Facebook and check your points on the Mlife site (even though the points won't be there for a week). The site was running a little slow for us so be patient. The promotion is good for the month of August. Here's the legalese for those that like that stuff:
