I might have incorrectly understood this post, but I just got a different response from SPG:
On April 17, I sent a fax to the (512) # per the
Starwood Lurker post, requesting SPG Plat based on HHonors Diamond. Got an email back today,
[yadda, yadda, welcome]... we have upgraded you to the Starwood Preferred Guest Platinum Preferred Level. This is a one time only exception. In order to retain your Platinum Level membership, you will need to have a minimum of twenty five stays or fifty room nights. This number is based upon a calendar year basis, January 1 through December 31.
Is that pretty standard? Don't get me wrong, I'm very pleased for the match and I don't imagine that I'll have a problem retaining the status come Jan 1. But it doesn't seem like SPG comp status always lasts at least 12 months.
