i think 'answer' to your main question is discussed here more generally

when (good) companies say they focus on service, that is true
programs cost, and are designed to be profitable within program

i dont think you were suggesting cheap chain hotels have same budget as expensive top property, but properties/locations will vary. luxury non-franchise vary much less, but still vary.

service is not always about quantifying, and when 'MBAs' claim you can, that becomes problematic.
