Congrats, welcome to the Insiders, learn those differences from Gold to Platinum. Don't get overly excited about the UA and Marriott partnership unless you can find some silver lining (pun intended) in Silver status with them.
Plus, it ends 1/31/14 and we're certainly not getting any vibe from Platinum service reps that they have heard about any extension. I've asked 3 Plat. and 2 UA Premier reps. Let's hope that's not your raison d'etre, we need your ongoing insights (I had snails recently/not escargot; wanted to avoid two French terms in one sentence, don't want you to think I'm going all fancy pants on ya ).
You get a nice 50% point bonus for your stays to go along with a welcome gift of 200, 400, or 500 points depending on brand. These can add up quick.
If you made Platinum from your stays..75 nights... let's figure you checked in at least 25 times. Those 25 check ins at 500 points bring back 12,500.
If your nightly rate averaged $130, your 75 nights will bring 97,500 points...your 50% bonus brings another 48,750...
So your extra Platinum points would be 12,500 plus 48,750...or 61,250. These will help you schedule a very nice trip!!
Congrats on your achievement, clark3.
