We stayed at the Gran Hotel during family week, which was Chilean summer in February. No one dressed too formally for any of the meals, but men were to wear trousers with shirts or sports shirts for dinner.
We wore shorts to breakfast or lunch because we usually had activities scheduled throughout the morning and afternoon. My daughter-in-law and I are dressed for dinner in this picture, perhaps this would be considered as "business casual".
Fondest memory: There are so many wonderful memories from Termas de Chillan: the superb pampering of the guests, sumptuous meals, excellent service, exciting activities all in a spectacular location!
If you take good advice and rent a cabin while staying in Chillan, it will more than likely have a bbq pit to cook on. Everything that you need to prepare a meal for a dozen costs about $3 per person.
I suppose I was made the grill master because (I'm from New Orleans)? Anyway, I had at least 20 pounds of meat and vegetables firing away on that pit. I smelled like a forest fire afterward, but everything was cooked perfectly, brisket, chicken, zapayo, assorted vegetables and sausage.
