Trying to book a trip for November and was looking at the MGM Signature. I know that the casino, restaurants, etc are in the MGM Grand but my question is how do you get to MGM Grand from the Signature? Is it a short walk? I just had knee surgery and I think I'll be able to handle short distances by then but nothing too do distant. Also, are the rooms there nicer than the ones in the Grand. I'm looking at the one bedroom balcony suite at the Signature. Lastly, is the airport check in simple and convenient to use or does it create any problems when you arrive at the hotel. Thanks in advance!
