Ok, woke up very not so early and took it easy: got a very good money exchange deal for £100 I got BR 285. In London I would have received £260 - so take my advice and don't exchange any £ at airport in UK or Rio-damn I sound just like Martin Lewis of moneysupermarked.com
I went for a long walk on the Copacobana, 2 hours at least and yes I had 2 drinks, no not what you think and you would have had =caipirinhas+e+caipiroskas , I had two coconuts drinks. Fabulous! Weather was not too good but hey who cares when you are lucky enough to stroll along the Copacobana.
