1) Does it make sense to rent an apartment for 1 week in Santiago (instead of hotel) and take day trips?
2) for instance could we just take a bus and go to Valparaiso for the day? Leave early, come back to Santiago late?
3) What is best to go from Santiago to La Serena? Instead of flying, could we just rent a car in Santiago and drive the 7-8 hours and then we don't need to rent a car in La Serena (we definitely would like a car there to explore the region)
