For PoP, we will be arriving a day early (hopefully so will the luggage). Does anyone know of a private operator where we can get picked up at Buenos Aires airport, have our bags shipped to hotel while we fly to falls, then fly back to BA that evening? Is this even worthwhile to try to do? Should we just postpone seeing falls until we have more time? If our flight from US is delayed, is there any way to avoid a 100% cancellation fee on such a trip?

thanks,
