I got there early and couldn't check in until there was a room available which was around 1. I didnt have a standard room and traveled during peak time for a conference
I only stay at MGM international hotels. I know New York-New York you can check in at 10:30am.
Check their website. We ate there. MGM is beautiful, lots going on. Normally 2 or 3 pm. I'd check on their website or call.
I only visited the MGM don't have any hotel information. Sorry!!
