When I used a suite-upgrade at the Hyatt French Quater New Orleans, I was upgraded into one of their junior suites. So my assumption was that the All-Inclusives were not eligible for suite upgrades.
I reached out to Hyatt just to confirm my suspicion, and was surprised to learn that you can upgrade your stay into a real suite. Since the properties aren’t open yet, you cannot apply your suite upgrade until the hotels actually open–which is tomorrow for the Zilara and now for the Ziva.
I have a junior suite booked for the Zilara, so I’m going to try this out tomorrow and report on it. But getting a nicer suite out of a suite upgrade would be sweet, indeed!
