My wife and I did the full day cooking class along with two other couples. The grounds of the school are wonderful, and we enjoyed the quick walk through the herb gardens outside of Hoi An on the way there as well.
We felt that the chef on the day was just going through the motions, it was all blah blah blah, do this, chop that blah blah, he wasn't very interested in doing any more than the minimum.
I guess you can understand that if he did the same old thing day after day but we asked him if he does the tour every day and found he only did it occasionally.
He wasn't invested in us or the class and at the end he just vanished, the class were sitting eating what we'd made and we never saw him again, another young lady appeared from somewhere and bundled us into a boat and sent us on our way back to Hoi An.
So we didn't think it was worth the money and we have done more interesting cooking schools elsewhere.
