A question about the cost.
The official website lists the price as R$46, which includes a RT tram ticket and admission to the monument. If you take a taxi up instead of the tram there is an additional cost for the taxi. Also I gather that the taxi does not go all the way up. I presume you get up the rest of the way by official van which is included in the $R46. So basically you have to pay the R$46 and an additional amount for taxi if you choose to use one?
