Hmmmn, I'm surprised to see so much love for Pier 39. I hadn't been there for ages, but when my cousin came to visit a couple months ago, of course we had to go. Pier 39 is a must see on the tourist trail. Granted, the views are amazing from the end of the pier and the sea lions and you have to stop here to buy tickets to Alcatraz...but other than that, I don't like it. Lots of tacky shops selling generic souvenirs, overpriced restaurants with mediocre food, weird street performers. Take your relatives here for a bit and then move on to the better sights.
