My husband and I and another couple are going to Santiago in the end of January for two weeks. We would like to see some old friends outside of Santiago, Talco and maybe Osorno. We would like to also see a winery go to a beach and basically see as much as possible without being exhausted as this is a one time trip. Any suggestions on where to start. We will be renting a mini van(?) Also, should we be booking places to stay now or play it by ear when we get there?
