MyVegas First time using myVegas rewards?

I have never used myVegas rewards, but have the app and am planning a trip to Vegas in April. Sorry for the simple questions, but I didn't find any threads answering my specific questions. I am staying at MGM Grand but booked through expedia and I also just joined Mlife rewards online. So I wanted to be sure I am eligible to get myVegas rewards and how would I go about redeeming them. Thanks in advance for the information!

 

You will need a Facebook account and log into the game on your phone and "link" the mobile app with your Facebook account. After that, you can redeem for the rewards through your phone or through Facebook. Make sure the first mLife reward you redeem for that you use your legal name and a valid email address as those will be linked to your account going forward. Once you are in Vegas, just go to the Players Club desk and either show them the confirmation number on your phone or a printed out copy of the email along with your identification (and mLife card if you have it by then.) They will get you set up from there.
