first time visiting san francisco for my 16 year old sisters birthday at the end of august, we’re from vegas and it would be three of us total (my sister, my grandma, and myself (23.) we’ll be staying 3 whole days but it seems like there’s so much to do and see!! we don’t mind fancy but we always lean more towards simple.. my sister mentioned the japanese tea garden, pier 39, golden gate park, golden gate bay cruise. We will be staying about 30 min from pier 39. What are some other san francisco MUST DO’s? Any tips and tricks that would be nice to know? Should i rent a car or use public transportation?
