I thought I'd get free parking using my GoH award, but I called Hyatt customer service and they said that you are only able to get free parking as a globalist if you use a free night award or suite upgrade award. Although I have these awards, she said I wouldn't be able to use them with the GoH award.
I'm an explorist, using a GoH award for the first time. Staying at Hyatt Regency Chicago. I booked the stay with points + added my GoH award.
Not posting to say there is anything wrong with what CS said. Just sharing my experience and hope to provide some clarity on this issue. When I read through the questions asked about this previously, there are mixed answers.
