So we got an awesome deal on a flight into Sao Paulo and out of Rio, $440 round trip per person.

We have 19 days to split between the two places OR we can split them between three places, sandwiching Buenos Aires between them. We both want to go there and had considered just visiting there when we had a little less time.

The trip from SP to BA to Rio adds considerable expense to the trip. $575 each for the round trip tickets, plus another round trip to/from an airport, so basically we are talking $1200 tacked onto the trip to go to BA for about six days.

However if we took the trip separately it would cost us as least $2000 and a lot more travel time (this is a 2hr45min flight as opposed to minimum 10 hours each way otherwise). The advantage would be that we'd have more than five or six days to spend there and maybe go to Patagonia and other places in Argentina.

What would you do? I have the money but I am wondering if it's good use of it or we should just split the time between the two Brazilian cities.

And you will know MY JACKET IS GOLD when I lay my vengeance upon thee.
