If I'm traveling internationally outside of the US, will the hotel room get charged in local currency or based on what is selected on Hyatt website? When looking for hotels on the website, there's option to select different currencies or the local currency. Will they charge based off of what you select or always the local currency?

Another question is when do they charge my card for listings that show:
Deposit Policy
Credit Card Guarantee Required

Thanks so much for all the help!
