The overhaul of the loyalty program is WAY overdo. The program is unsustainable. When I read about the Disney program, I thought it was too weak to make any difference. I have personally heard about changes from mgt going back to when the Splendor came out and they hired Hana away from Starwood loyalty (I think it was).
The fact of the matter is that when half the ship qualifies for the “program” it needs to be scoped down, significantly. I doubt very much very there change will only be the Disney or MSC versions. Look for somethingwhre they raise the bar for the top two levels and add a third level (just mho).
