As of now, thanks to the 15 CC nights and the Double Elite Nights promo, I'm sitting at 96 nights and have spent $8297 over 62 paid nights (~134/night). I have a two-night stay coming up that with the promo will put me at 100 nights, but my rate is such I expect to have just under $400 qualifying spend.
Funny you started this thread- I was going to post something similar in the big "Ambassador" thread when I cross over, just for a laugh.
My spend is all out-of-pocket and with FIs in CA easily going for $300/night, I sometimes have to plan my trips around stay rates.
