unique idea for san francisco attractions.
I went with my wife and daughter to San Francisco for work and bought some of these cards so they could use them during the day. I didn't buy one but I wish I did because it ended up saving money and trouble. Together they visited the Cable Car museum, trolley hop tour, Six Flags marine wold, Zeum and i guess they got discounts on food, too. The guide book helped my wife navigate herself around town--and she said it was a lot less stress, too. I was very impressed with this product and would recommend it for other families too.
