A vacation you go on while pregnant as one last trip before the baby comes.

Time off from work taken by new parents to go to the hospital/birthing center/Wal Mart/North of US Border in order to give birth to a baby. A babycation optionally includes extra time to get used to having a baby at home. This time is used to get used to getting no sleep, and adjusting to the nigh constant smell of putrid milk associated with baby spit-up.
