Brazil - am I getting the best from my trip?
I have just managed to get an award ticket on LH (in F- ^ ) down to Argentina and returning via Brazil. I have one week in Brazil, arriving on Christmas day - apart from Rio I am fascinated by the architecture of Brasilia and also would like to see the stunning theatre in Manaus, with a Varig airpass I could visit all three for not a lot of money - but am I seeing the best of Brazil? Any thoughts? are there better places to see/go?
