The Nightly Rate Beneath The Day Rate

September reads $192 and runs 16 percent above the city average. March reads $197 and takes the top of the twelve-month table. December reads $129 and takes the bottom. A 35 percent gap separates the cheapest month from the priciest.
The organiser's eight hotels publish no day rate and no nightly rate. The brand band is the only published discount figure on the market.
