Some casinos will offer discounted, upgraded, or free tickets to their live shows as comps. Free tickets, especially for headliners in Las Vegas, generally are reserved for the high rollers, that is, those betting $100 or more per hand. But moderate bettors often can get either discounts or better seats by talking to a pit boss or casino host. Just as the casino reserves hotel rooms for its rated players, most showrooms reserve some of their best seats for players. Your best option is to check with the casino host to find out what special entertainment offers you might qualify for.
