To protect this revenue stream, most hotels include minimal spending on food and beverages in their contracts. This is simply the minimum amount of food and drink with catering that you must spend during the meeting. Most venues offer a higher minimum of food and drink on Saturdays than the rest of the week, since Saturdays are in high demand. How much less is the minimum on other days? It varies.
In general, a few thousand dollars, not so much as 50%.
