We just checked into the Park Hyatt in Buenos Aires and so far everything is fantastic. We booked their driver for pickup at the airport, so they knew exactly when we would be here and we were able to sit in our suite very comfortably for check in. They were kind enough to give us a double upgrade to an executive suite, which is truly a great accommodation. I even have a separate cozy work space which is the perfect size for me, and keeps me from disturbing the wife. We are here for nine days and so far the hotel and staff could not possibly be any better.
