@jpm No worries - if you are currently platinum, and have 41 nights this year, your status for next year will be dependent on where you end the year. Worst case scenario, you will drop to Gold status for all of 2017 if you can't nail down the other 34 nights between now and year end. That's if you did nothing else. You will have options though.
As for the lifetime status counter, that is just telling you where you are against the objectives for lifetime status. You will need 250 for Silver lifetime, which you have. You must also have the 1.2 Million lifetime points to accompany it to secure the Silver lifetime status. Going up from there, Gold is 500 nights and 1.6 M points, and for Platinum you need 750 lifetime nights and 2 Million points.
It looks like you are well on your way, but you will need to make some decisions about next year depending on how this year finishes for you. You don't need to do anything right now, but you should begin contemplating how the year will end and whether you want to pursue retaining platinum with one of the above options.
I hope this was helpful! Happy traveling!
sunsoaker Other than the requirements for LTP, those were also much better traveling times than now as well...will be interesting to see what changes are in the works for 2018 and potential merging of the two programs.
