1) point posting - Hyatt's IT people are probably high school dropouts. I have been a Diamond for 6+ years and they have NEVER fixed that issue. I mean, how hard can it be?!@!!@?! I have GP customer service on speed dial, to correct the point posting issue. I am tired of hearing excuses that too many computer systems and too many hotels, blah blah blah, 6 years is a LONG time to fix a rather simple issue.
2) Good luck! the suite upgrade is another hit and miss thing. I don't even count that as a benefit because it never works when you wanted it.
Surprisingly, i did the opposite of you, I joined Hilton and I can tell you that Hilton benefits are much better and useful. I think you made a mistake...
