You will be in the main building. It takes a couple of days to navigate the hotel as it is so big, but you soon get used to it.
The Signature is 3 totally separate towers a 5 min walk from the back of the MGM. The rooms are all suites with kitchenettes.
The West Wing is the old part of the hotel and is near the Lion Habitat. The rooms there are really small with a tiny window. If they offer you an "upgrade" to a WW room at check in I would recommend refusing it.
The freebies you have on the 222 Offer should be charged to your room. You can check your account on the TV and they shouldn't show, but if they do just call the Front Desk to have them taken off.
You can also check out using the TV.
The monorail is at the back of the MGM for easy access to the rest of the strip.
I said that Vegas was quite quiet earlier on. That must have been a blip as it's really busy again.
Temperatures are a lot lower this year than normal due to El Nino.
