It is my understanding however, that no hotel will be able to waive the taxes AND give you the Starwood credit/points. Its an either/or thing, because you are either a guest at the hotel (and settle up every few weeks or so, so that no stay is more than 30 days) or you are a tenant at the hotel (where you get the taxes waived).
