I have been an HHonors Diamond VIP level stayer for many years, but have now twice encountered a curious verbal exchange. Both came at the Hilton Hawaiian Village, when trying to buy an upgrade. In those exchanges, approximately a year apart, I was informed that there were two "secret" levels above Diamond, but even the manager on duty, could not give me any more information, that that I was not even close to the "top." Does anyone know anything about those "two secret levels?" I sort of anticipate that they might be like United Airlines' Global Services - if you have to ask, you do not qualify. Hoping that the folk here can fill in the blanks for me.
