Planning for a fast two nights visit to Zurich was shocked from price deference between Government and Members rate

my stay well be 2 to 4 of AUG ,

Platinum Member rate 741 CHF or 764 USD
Government rate 595 CHF or 613 USD

764-613=151 USD

151 USD is this fair Marriott ?

I work for the Government out of USA , in my country the Government rate is higher than Member rate !! why Marriott ?

To Marriott, Member rate must be the lowest ..

how can they fix this big rate problem !!
