I remember that Intercontinental Hotels used to be fussy about recognizing their Ambassador program, but (I think) not recognizing status in the regular IHG program. The terms for Diamond status don’t list Intercontinental as excluded, so I assume IC are now recognizing Diamond or other status from the regular IHG program. So if i use this offer to get Diamond status, would that stack with Ambassador status? I have made an effort to find with Google, but don't see whether the programs stack.
