Visiting bay area - do I need to rent a car?
I am visiting bay area from Oct 22-Oct 26 for a conference in Sunnyvale on Oct 23 and 24. The hotel prices are already too high for these day and I am paying around $500-$550 just for hotel for these days.
For first 2 days I will be staying near Apple/Google campus in Sunnyvale and I wanted to roam around and look through those campuses of big tech companies since I will be around in the area.
Are the campuses nearby in walking distance or would I need a rental car too? I am trying to cut down the cost since for the entire trip I will end up with atleast $1000 of cost considering flight tickets, accommodation, food and parking here at the airport + uber/rental car.
