I'm considering traveling down to Argentina for the Copa America, how common is this? Would it be difficult to find rooms/tickets for games for this tournament? How much do other people from South America travel to see their nation play in the Copa America? Just curious and trying to gather facts. Thanks.
If you're a young guy there is no better city to go in South America than Buenos Aires. Just go man. And if you've got the money you'll find tickets and a place to stay. And you'll have the time of your life, believe me check this site http://www.airbnb.com/
It depends the city are you going to. At least in Mendoza, it's already impossible to find hotels, so the mendocinos will use their houses like "hostales" for the fans (specially Chileans, more than 40,000, plus Peruvians, Uruguayans and Mexicans). Maybe in San Luis will happen the same. Anyway, many Chilean fans will go for one match and will come back inmediately.
