I can't speak to Patricia Wells culinary school, but looking at her website I think that's a lot of money for what you get. I travelled to Tuscany in 2005 and spent a week of that trip at a culinary school. It included lodging at the 500 year old estate; daily classes; three meals a day; daily excursions.
The staff prepared breakfast. During daily classes, chefs gave a history of the dishes, demonstrated preparation, then students prepared the dishes. Most of the dishes were served during our lunch. Some dishes were reserved for the daily dinner. Every afternoon, guides and transportation were provided for excursions to places like Pisa, Lucca, Lerici, Carrara, and Viareggio. While out on excursion, the staff prepared the daily dinner.
I think adjusted for inflation, the price was comparable to what Wells' school charges, but offered a lot more.
Shortly after my trip, a couple from our wine club did a wine and cooking school in France. Their trip was a bit more expensive, but it too was pretty inclusive and had a number of winery visits and tastings.
