That is ridiculous that there is DCC at Marriott Sydney Harbour when you already pay an extra 2% just for using a credit card as payment. I strongly suggest going across the street to the ANZ bank and taking out the cash to make the payment (like I did). ANZ only charges 2 AUD as an ATM fee, and my bank reimburses that anyway. Even with having the MR Visa, I still was against paying the fee.

This is the merchant company that asked for AUD/USD choice for at least one of my transactions: https://www.tyro.com/

The terminal with the vertical chip insert is the Yomani box on this same page.
DCC is an option via Tyro as noted here: https://www.tyro.com/dynamic-currency-conversion-dcc/

They are not hiding the revenue enhancement fact with DCC.
