Hyatt in Santiago is to be the best hotel in the area. It truly is a magnificent property.SHeraton being second and it is nice as well. The Lake District, Northern Patagonia is beautiful. Chiloe Island is nice and has a lot to offer. Puerto Montt is nice too but it is just a town. I think that it would be nice to travel to one of the nearby islands to see some homes of the locals. Lake Llanquihue is great and offers some nice sailing. Have a great time and do bring a lot of dollar bills as they are exchanged in large amounts.
