I know that it's getting harder and harder by the day to book hotels and flights in ARS. Yet I found a website, which is still billing you in ARS at the official rate. I have used my international credit card and got billed in ARS.
Can local credit cards be used online to book hotels billed in ARS or is there a "lock" on them so that they cannot be used or only by paying a government tax (similar to when you wanna book a flight)? Since I have to book quite a few hotels next year, it would be nice to save a bit on them
