I use this as a revision task for Catering but would probably work with lower years. Students have to randomly select two different hospitality businesses and compare and contrast the different products, facilities and services on offer. It is a good way to get them thinking about the industry as a whole and explaining why there are such broad differences and opportunities in the industry.
This can be set as a homework or as class work, sometimes (depending on the class) I ask them to present their findings to the class. It can be very interesting watching a student explain why a school dinner is better than the food on a luxury cruise ship.
