If you're coming from Argentina you should check out Squaw in any case. I general if in Tahoe for a week I recommend splitting the lodging time between north and south shore for convenience.
If you're in south shore the whole time the drive to Squaw around Emerald Bay is very scenic and will take about an hour. But plan carefully:
1) Maybe not on a weekend when traffic between Tahoe City and Squaw can be deadly.
2) Be sure to do it on a good weather day when 89 will be open and the road fairly clean. But you want a good weather day for Squaw anyway so the whole mountain will be open.
