X2 - this is by far the best direct benefit to being Diamond. My favorite indirect (non-monetary) benefit is the Diamond check-in. You can easily wait 1+ hour to check-in to Caesar properties in the regular line. Even with the whole online check-in thing it's a total disaster during peak times. Flamingo Las Vegas seems to be the worst. With Diamond you just walk right in and are greeted with a bottle of water and a cookie!
