Which property? Saying it's a "Hyatt partner resort" sounds like it's not a Hyatt property, and just because it can be booked on Hyatt's web site doesn't make it a Hyatt property. If it's not a Hyatt property, you'll have to deal with the property directly and Hyatt won't be able to help you. If it is a Hyatt property, [email protected] may be able to help.
