If you got a three day card, yes. Once you start using it, you've got that day plus the other two to use it. AND, most places on there... No all the places on there, you can only use the card until 5pm. I purchased the big card with all the places on it, and we only went to like 2 or 3 of the places because the whale watching was 45 min away, and we only had to 5 to use it. Mine was a 3 day card. I didn't think it was worth it, because we stayed with friends and used their vehicle, so we never had time to use it. But we were able to go to Lego Land which was 45 min away. I enjoyed my time there, but wish I knew more about the Go San Diego card.
No, you can use it in a span of a week (I believe)
