You're going to leave with a bit of a sugar high...it is a great experience to tour the factory as it is quite interactive and there are a lot of optional things to do there, like the children's play area outside and an experience where your chairs move and you're wearing 3-D glasses, all included in the price of the ticket. I could see this being an all-day event for a family.
You get multiple free bars of chocolate throughout the tour as well as some melted chocolate at one point. Their factory store has really good deals on chocolate and gifts.
