I sympathize with OP's dilemma, having been in a similar situation. Agree that Hyatt should have a better way of handling this issue, consistently applied across all properties. At the same time, a wealth of Flyertalk expertise has weighed in here, suggesting that for whatever reason a resolution is not likely anytime soon, any Hyatt assurances to the contrary notwithstanding. FWIW, I agree with that perspective.
With all due respect, at this point the tenor of the OPs continuing posts suggests to this reader that OP is looking for validation of a predetermined conclusion, rather than simply for others' expectations "about situations like this." The good thing about FT is that you will have plenty of supportive opinions to choose from!
