Adding in taxes adds about another $200. Also, check the fine print of your specific offer. Mine doesn't include parking which add another $15-$20 per day depending on self park or valet. On the other side, however, when I called they told me that because it is a rental, you do get daily housekeeping. Interestingly, most offers, per the rep, stated that wi-if and parking were included in previous offers, so he was surprised my offer excluded parking.
And, they stated that it was a targeted offer and couldn't be used by anyone else. I was surprised because we had friends wanting to do the offer and easily qualify, but when they called they were told absolutely they couldn't sign up if not on their name list .
