Ok my turn to ask

Thanks to Gaucho100K for his PM in encouraging me to go.

I will be going to EZE for 2.5 days, alone, and will be staying at the Park Hyatt. Would like to do a walking tour but I either arrive 10am or 11pm xmas eve, haven't decided which airline I am flying and will fly out 10pm day after xmas. So really only 1 full day to enjoy (xmas day).

Gaucho100K has mentioned restaurants will be open but will the menus be like $100 USD min?

Any private walking tour guide that will work that day?

Where is a good place to change money once I arrive?

Any party scenes xmas eve or xmas day? I don't mind going to a bar alone

2000AR should be enough for the time I am there? Not including hotel room/air, just for cabs, food, drinks etc.

Thanks all!
