It looks like Hyatt got its system cleared up with the All-Inclusives. The readers who were reporting getting quoted 50,000 points per night by phone reps have now been able to book their stay at the Zilara for 25,000 points a night. It looks like things got fixed in their computers!
I tried calling for my suite upgrade, and the system is now allowing it, but it isn’t attached to a specific room type yet. It looks like the new property is on its way to being bookable, and hopefully things will be set in the system in the next few days.
