Thinking about making my first trip to South America, specifically Buenos Aires (with possible side trip to Mendiza) in July, as I like to take a trip someplace new for my birthday every year. I know July will be winter in South America, so I may encounter some variable weather, but what should I expect in terms of level of activity? I imagine this may be "off-season," so is there a slower pace, different level of service, location closures, etc? I'm really interested in wine and might want to take a side trip to Mendoza - would wineries be open for tastings/tours this time of year? Sorry to be a bit general in my questions. Really just trying to get a sense for what I might expect that time of year to help me decide on whether or not to make the trip then or postpone to another time. Cheers, all, for any advice you can share.
