The Booking.com rate you have confirmed is the rate available to the public. This OTA and others will enjoy in the vicinity of 20 percent commission, which is why I advised the Net Rates.
In any event we are poles apart on rate, so let's agree not to pursue this opportunity further whilst you offer corporate rates that are higher than dynamic OTA retail rates.
Your product would certainly suit a lot of our patients, so please feel free to reach out to us in the future if you wish to have a further discussion based on net tourism industry rates.
