Another data point
I just checked my account for some upcoming stays and noticed that I've now got Royal Ambassador and Kimpton Inner Circle status. I wasn't expecting it as this is my first year where I've stayed regularly at ICs and I only had a total of 31 nights at IHG hotels. I did have a few expensive stays and ended the year with about 250K EQP. I had 9 IC stays (5 different hotels) and 2 stays at the Kimpton Fitzroy. One lonely CP in Niagara Falls on Boxing Day!
