8. Not taking advantage of the casinos’ rewards programs
At most casinos, you can earn points for pretty much everything, and use 'em for almost anything, including dining, entertainment, and upgrades for hotel rooms. So if you don’t enroll, it’s almost like turning down free money. Pro Tip: Among the best are M Life from MGM Resorts, Total Rewards from Caesars Entertainment, and Backstage Pass from the Hard Rock.
