Accor has been quite aggressive in Brazil lately. And another hotel seems to be opening soon. Accor's Fairmont Copacabana is scheduled to open on April 1st, 2019. (It's not a prank, hopefully :P ). And Accor is offering 1000 bonus reward points in case you are not the type to read reviews first and then decide. It's a different experience to stay in new hotels. This could be one such opportunity, if you happen to be in the city. 

You need to register for the offer first.
