I was gonna say about the same. We used our DVC or AP discount. We loved the behind the seeds tour. I was just us and another family from California. They were walnut farmers or another nut. They were the nicest family. Very Cool tour! Our daughter was 13 at the time and loved the entrie tour.

When I just did it a few years ago, it was between $12-$15. Very well worth the tour if you like the living with the land ride. Very educational about the advancements that are being made in farming.
