I did it a couple of years ago. Like Lancer said, you get to walk around in the greenhouse, which you see on the boat tour. Some of it was interesting, but DH and I were honestly bored and thought it was too long for us. We just tried it for something different. But I did learn a few things that I still remember, like about hydroponics. I'm glad we did it, but I wouldn't do it again. If you're interested in gardening, it will be fun.
