I'll be arriving at EZE late on a Saturday night. I have no general objection to taking the bus from EZE to Retiro and walking what appear to be less than half a mile to the Marriott Plaza. But as an obvious tourist with bags and all, I'm certain I would be a preferred target. (1) Is this walk safe at, perhaps 11:30 on a Saturday night? (2) do taxis at all queue for the busses coming from EZE (I am gracious enough to pay a premium over the typical .5 mile cab fare) (3) should I just pay what it takes for a taxi from the airport?
