godshall2,Hope you don't mind a comment from a beginning web designer. I'm certainly no expert, just opinionated!
I really like this design! It's simple and classy. It's not blah but I agree with you that it could use just a touch more color as accent. Even the color picture seems pretty neutral in color to me. Perhaps a good coordinating color used in the logo, maybe just the Las Vegas part of the text? Then pick up that same color in your navigation buttons by having the text change color on rollover. A lot of what I have seen lately in graphics design for printed ads, and for web design makes use of black and white or neutral colors with a single brighter color for accent.
