We just got a quote for a private tour for four people. This is the long day's itinerary:
Pick of at ship upon debarkation at about 9:00 A.M.
Tour of Valparaiso
Tour of Vina del Mar (Wine growing region and several wineries)
Tour of Santiago
Transfer to airport at 9:00 P.M. for 11:30 P.M. departure on American Airlines
This tour is quoted at $70 per person including a tour guide. I think this is a great deal. If anyone else is on the Zenith, they may want to try this for their last day.
