I have been silver for 3 years. When I first logged in to the Mega Bonus promotion, it said I needed to stay 10 nights for 10,000 points. Then when I checked it several times on line in March and April, it said that I would get 20,000 points by meeting the challenge. Well, I just completed my 10 nights and logged in to see if my last nights were credited. They were, but no Mega Bonus points were credited. And now it says, my bonus will be 15,000 points - not the 20,000 points it's stated for weeks. What's up with that? Why do they change the award now?
