How do i do this? I will be in Ush Feb 2nd and want to head out of there and get to El Calafate and alsoIguazu falls? I fly out from BA Feb 13th. How long to spend in each place. Any special deals re the Igu park and acc. I am a seriously low budget person, but when htere is a deal i can be tempted. Are bus trips out of the question ad totally no recommended?..
