The compensation is for the entire stay.
We walked up to the Premier village with the activity team last year, as they had only a soft opening, they would not let us visit a room.
My understanding is, that even though it is the same Vietnamese owner as the JW, this one is under Accorhotel management. They don't have this beatiful French colonial style that I appreciate at the JW.
A new Sheraton will open next year after a 2 years delay, will see if we go there if we ever come back to Phu Quoc
