There are aspects of luxury that aren't scalable due to scarcity. For example, if you have a hotel located in a historic building in the center of a small village or a castle hotel with some particularly special view, you just cannot duplicate this. Similarly, there are a limited number of truly great chefs in the world and some special ingredients are limited too. Of course one hotel could attempt to buy a top chef for itself by spending money on salary/staff/kitchen/dining room, some other place then would lose its top chef. In the longer run, industry groups could encourage and subsidize training, but I'm inclined to believe that the real cap is that talent of this caliber is truly limited.
