First the good news: Las Vegas property level EBITDA margins have expanded 10 out of the last 15 years and were 4% higher in 2007 than the average over that period. The bad news: Mean Reversion is probably rearing its inevitable head. Why am I concerned about mean reversion? The impressive margin expansion was driven primarily by the hotel and the food and beverage product lines (casino margin has been stable) which should contract first and most dramatically as consumer spending slows and probably recedes. The following chart clearly shows the relevant trends.

In 2007, rooms and F&B contributed 40% of revenues and 38% of total departmental profits in Las Vegas, big contributors for sure. Room rates are already under pressure and casinos won't drop occupancy to hold rate. ADR's are the highest margin revenue source in Vegas. Do you see where I'm going? I'm not sure F&B traffic and pricing can hold up in this environment either. Restaurant traffic certainly hasn't across the country.
My partner Keith McCullough constantly reminds me that context is not just the last few years. Context in this case is at least 15 years. Unfortunately, when it comes to margin mean reversion, this context is not very comforting.
