I asked Hyatt about the Andaz Scottsdale providing only complimentary water as their free minibar offering, and charging for other non-alcoholic beverages and for snacks. They told me that the brand is rethinking its minibar offering, and in the meantime “properties can determine what minibar selections are offered on a complimentary basis.”
However they’ve since followed up to clarify that – in fact – it turns out that this flexibility is only meant to apply to “the specific types of non-alcoholic beverages and snacks that reflect their destination” and they are still requiring “items beyond complimentary water.”
