Been to Vegas quite a number of times, but haven't stayed at either of these hotels. Through Mlife, for 3 nights (excluding tax and resort fees), I have $307 for Aria Deluxe room and $228 for MGM Grand King. Which one do you recommend? I stayed at Mirage, TI, Caesar's before, as far as comparable resorts are concerned. I like to play blackjack and slots. Is the price differential worth it for Aria? I guess MGM's rooms are newer, so could it be a better deal?
