Not too familiar with the Fun-Nite chips. I do recall seeing some on eBay once. Can't remember which hotel they were from. One of the newest ones in Vegas. As I recall, they were given out to select guests who attended a party the night before the casino had it's grand opening. I do not know if they were for playing for fun and or charity or if they actually were redeamable. I got the impression that they were used for Playing for Fun.
