What are the benefits of touring the hospital?

Knowledge. Just knowing where you are going and what the rooms look like can allay fears and decrease anxiety. For many women this is their first time in a hospital and they may be frightened.
Familiarization. One the big day the last thing you need is to be confused about where to go, how to sign in, etc. Touring the hospital allows you and your partner to take a dry run of getting to the hospital, parking the car, finding labor and delivery, etc.
