With the immense size of Buenos Aires, there is one thing for certain, you won’t run out of activities to keep the whole family entertained and no matter how long you are staying, I can guarantee you will definitely enjoy yourself.
Throughout most of the year it can get quite busy in Buenos Aires but throughout the hotter months (usually December – February) the locals tend to leave the area and decide to have vacations elsewhere so it is possible, you may not come across as many locals but overall, tourists tend to visit all year round due to the range of annual activities that take place.
