After 15 cruises on O in PH to Insides, I have never seen anyone transported to the dining areas on the arm of their butler!! Also, never met anyone that has regaled me with stories of their butler doing anything for them except to say how nice he/she is......so no we have never met anyone remotely like you are describing...
Access to the spa area is complimentary for Concierge and above but available to anyone on the ship that wants to pay for a day pass (pay for access upfront or as you use)....
Class system is when certain areas of the ship are not available for anyone not in a particular cabin category - expect for the 2 lounges, there is no where on an O ship that is closed to anyone onboard.
