MyVegas Question with stay requirement and rewards

I have a one night reward for the Monte Carlo. I also got the monte carlo breakfast buffet and the Aria lunch buffet. I want to check out of the Monte Carlo early in the morning and switch to the Cosmo if my room is ready. How long do I have to use the reward? Do I have to redeem it before I check out or can I use it the same day I check out? Like can I redeem them at players club before I check out and then use it a couple hours after I check out?

 

Yes I did. Just make sure you load it onto your card at the Mlife desk before you check out. They will ask you what day you want to use it and as long as it is over your stay you will be good. We checked out a noon on the Sunday and used the Aria dinner later that evening. We loaded the reward onto the card when we arrived at the Aria a couple days before.
