Question about hotel stay

We want to purchase the Aria lunch buffet which requires a 1 night hotel stay. How would we be able to use this lunch buffet, since the hotel won't let you check in til 3:00 or 4:00, well past the lunch hour, and check out is usually by 11:00, before the lunch would start. Maybe I'm missing something.

You should have a reservation number for your hotel stay, present that to the people at the M Life booth and you should be good.

Thank You. I was hoping that would work, as I only want to book 1 night thru MYVegas, because my other nights are comped elsewhere.
