Just signed up - This is what I was told
Just signed up.
Sign up for either Gold or Platinum
Need 12 days for Gold - 18 nights for Platinum
During the next 90 days, after you sign up, you have to meet the challege stay nights. if you meet the challenge, you remain that level for the rest of the year and the next.
If you not meet the challenge, you revert back to original status, which in my case would be 'member', You will not be allowed to try again until 1 year later.
So I signed up on Feb 9, my first stay is the 13, and I will be checking in as Platinum with all the benefits, bonus points, etc.
This is a great deal.
