We're arriving in Santiago on 15 November 2011, were thinking of going to San Antonio for a day or two then on to Rancagua for a weekend visit to Sewell as tours only go then. But it looks as if the Criollo festival may be on during 18-19-20 November. Have searched the Web for hours, can't find it! Can anyone help, as if it's on we'll forget S.Antonio and go direct to Rancagua.?
