You can put a little power on the engine (6-7 deg. PLA, methinks) up to the gust lock stop. V. efficient for opening the HP bleed to get the most out of selecting the aircon to HI FLOW.
Hotel mode operation tends to be detrimental only to 1) ground crew comfort 2) crew inside the aircraft if wind is quartering from the rear 3) paint job on aft part of nacelle 4) pilots ego if you forget the max. tailwind component
