18+ for the MGM Grand. It is one of the few in Vegas that allow 18 year olds to register. You can see what hotels allow under 21 in Vegas on this page.How old do you have to be to stay at MGM Grand?
call and ask....

with an adult or without?

If you are 18, I believe you can check in at the hotel, but you will not be allowed to gamble...

21 yrs old at MGM, 18 yrs old for something off the strip
i,m pretty sure 18, but you cannot go to the casino.
