not sure if there is anything short term but to get the lifetime status you have to achieve a certain number of nights, for platinum its 1000 lifetime nights, 2.8M points (I think?) be in the program 12yrs and attain platinum along the way (someone correct me if I'm wrong on this).
Until now those total nights were somewhat of a guessing game for most people. It could also play into being given the Plat Premier status but as there is no published steps to achieve that rating, we cannot be sure.
Hope that helps :)

As our ambassador has informed the community, we wanted to share with you a few updates made to all Elite level Lifetime criteria. As noted, the requirements regarding years enrolled in the program (at least 12) and nights stayed will not be changing. The main changes impact the point threshold. With this in mind, requirements are now as follows:
Achieved Silver / Gold / Platinum Elite status one or more years
Earned at least 1.2 million / 1.6 million / 2.0 million points
Stayed at least 600 / 800 / 1000 nights
Zukracer - an e-mail to email@example.com can get you your total lifetime points earned. In addition, you can ask about status level changes over the years and they will reply with details as to when you first reached each status and the month/year you did so.
Just a note, for the new website, to now see how many total nights you have stayed, you can do the following:
Go to your account activity page and select the link to the left for "Last Tansaction". When that page comes up, you will see a print options over on the right side of the page. If you select print (even if you don't have a printer attached), you will see a print preview page. Up towards the top left of the page you will see Total Nights Stayed.
Actually ssindc had mentioned that they had to print out a statement and that it was on there. Someone else said they had an iPad that wasn't hooked to a printer and that sent me looking to see whether a print preview window would pop up and if it had it there. Thanks to ssindc for seeing it first on a printed copy.
