We will be flying into Santiago and then after a few days heading for San Antonio which seems to have replaced Valparaiso as the departure port.   I am losing sleep over which option to take in relation to getting from Santiago to San Antonio.   One option is to get a taxi from the hotel to the bus station in Santiago, then the bus to San Antonio, then a taxi the the port. The other option is to take a private transfer direct from the hotel in Santiago straight to the port in San Antonio.
