It’s not easy to get comped for just betting sports. A weekend comprising $5,000 to $10,000 in action might get you a meal at some places. Your best bet for that is probably a Coast casino (Gold Coast, Orleans, Sam’s Town, Suncoast). As you move up the ladder to better casinos, the requirements escalate. MGM Grand requires a minimum of $10K per day just to get rated.
One of the problems is that your choices for sports betting comps of any sort are limited, because casinos who use the chains, e.g., William Hill and Cantor, are out. In these cases the sports books aren’t owned by the casinos, so your betting action doesn’t get you direct comps. Most have arrangements in place and really big players will get taken care of, but the emphasis here is on "really big."
If you want a comped room, your best shots are at Westgate (formerly LVH and LV Hilton), Golden Nugget, the Coasts, South Point, and Wynn, with Wynn being the toughest. The best way to go about it is to simply call and ask how much per day you have to bet for a room. Talk to the sports book directly, which may assign you a separate betting number to affix to your account; otherwise be sure to present your players card when you make your bets. Just to give you an idea of how much it might take, most books comp .25% or less. At .0025, it takes $4,000 in bets to earn $10 in comps. If a room goes for $80, that means you need just north of $30K in action per day to cover a room. This is why many competent sports bettors rely on other games where they can also get an edge to secure their rooms and other comps.
Horses are different. You can get comped via the race book for $5K-$10K in action. Sports requires much much more.
