Just a note to let you know our Brazil tip was great fun and went off without a hitch, thank you so much for organising it. Of particularly note, the guy who collected us from the airport was a hero, very helpful, skipped queues for us, etc. Made everything really easy!
The Sofitel for cocktails - was an awesome recommendation, we loved it! The Vegan Social Clube - slightly dodge, grey soup! But any port in a storm and it was good fun.
Pantanal was amazing! More of a bird watcher thing than we expected but great nonetheless. Pousada was incredible too, only 5 others there with us :) Our guide Carlo was first rate and the food was really good.
Brasilia - well, never mind...! ;) but it was only there to get us on our way to Miami.
We're on our way across the states now and struggling fending for ourselves after the spoilt treatment we got in Brazil...!
So thanks again, we'll definitely recommend you to others (in fact, already have).
