As I am moving closer to my travel date to Vegas later this month, I have been advised by this forum to start playing the free games on MyVEGAS app in the hope of earning some free comps. What I have noticed is that most of the buffet selections (without the one-night stay requirement at MGM properties) are sold out. As I will be staying at a Caesar's property, I can't satisfy the MGM hotel-stay requirement. So my question is: for those "sold-out" buffet comps, how often are they updated and become "not" sold out? Do they update, say, every day or every week? Or does this "sold-out" just means they are really sold out for the next 30 days? Any color is greatly appreciated!
