Had been saving a Platinum Extras Certificate for a stay at the GH Kauai intending to redeem it for the Welcome Amenity. At checkin last week, the agent said she had never seen this type of certificate before and didn't think it was valid at the GH Kauai. She checked with the front office manager who said it wasn't, but they would make an exception and honor it. They said they are familiar with the certificate you get when you qualify/requalify for Platinum [they only referred to it as the "cream colored certificate"] which CAN be used at the GH Kauai (I actually used mine there previously without any problem) but, they do not accept the white Platinum Extras Certificate with the silver/gray on the back. I really don't see the difference, but there's probably more to it than I understand.

I emailed GP Customer Service and they said that acceptance of the certificate is essentially at the discretion of each individual hotel/resort and cited the terms on the certificate which say:

"This promotion is subject to the Terms and Conditions of the Hyatt Gold Passport® program. The use of this certificate at some destinations is subject to government approvals, regulations, restrictions and applicable taxes and is void where prohibited. Hyatt reserves the right to alter or withdraw this program at any time without notice."

I asked if Hyatt or Gold Passport maintained a list of hotels that do not accept the Extra Awards certificates and GP Customer Service replied no. This being the case, it's possible that I could end up saving a certificate for a specific stay, only to find out at check-in that the particular hotel doesn't honor it. Should the expiration be nearing, I may not be able to use it in time for a stay at another hotel, which would be kinda unforunate.
