You are correct. I can see award rates for the Cat 1 & 2 hotels (5000 and 9500 points respectively which seems reasonable) but then it shows the message below.
Disappointing that Hyatt is allowing the hotels to just block out entire month for award bookings. Never come across this type of block before.
Have you tried calling Hyatt to see if they can help?
Unfortunately, this hotel is not accepting World of Hyatt points or award during those dates. Explore our other rates or modify your search.
