My boyfriend and I are travelling to Buenos Aires staying for a week and then hoping to travel by bus up to Rio De Janerio for our flight back to the UK. We are keen to see Iguazu falls on the way and have about two weeks to do it in. We are travelling in mid June so really want to catch some sunshine and hot beaches. I have looked at green toad bus travel but heard a few bad reviews.
If anyone knows of a route to take and good bus services.
