I know I am the type of person to go stir crazy stying in after a birth and was out shopping early too, but the more I read about the sensitive, delicate postpartum period, the more I think the advice of lying in for at LEAST 8 days is completely spot on. I think if you can honor yourself and recovery in the early days it takes a shorter time to recover overall.
I would absolutely not plan on going to an amusement park at 2w PP. I do know we went to a wine festival when my second daughter was a week old, walking around, in the sun, etc., and between me and the kids we lasted about an hour. It was a family tradition to go, but we basically made an appearance and bailed. Though I guess it depends on how you're feeling, if your bleeding has stopped and you don't feel sore, it could probably be all right, but far from ideal IMO.
