I am heading back for the 6th time since January and this time of year it is easy to get deals. My advice is to actually call around, the int'l long distance charges will be gained back ten-fold if you work the conversations right and talk to hotel managers. Let them know that you will be there and that you plan to come back often and are looking for a "home" hotel. I have settled in at the Park Tower in Retiro for far less than any published rates and I just jot the hotel manager an email when I want a room and my rate has stayed good for almost a year.
