I wonder how W bar and nightclub revenue is counted in these numbers. That's obviously a big difference compared to Courtyard. However, in some Ws, the bar/club seems to be operated by an independent tenant, while others are part of the hotel's operations. [It would be difficult to envision a pool bar as just a tenant sharing the swimming pool area.]
Similarly, in the Houston example (a market I don't know well), perhaps the JW has more/larger restaurants or perhaps its location makes guests more likely to eat in the hotel's own F&B outlets. Or maybe the JW just has some sorporate contracts involving high spending guests with liberal expense accounts policies. (Does anyone remember Enron?)
