If you teach hotel trainees, this is a simple but effective worksheet. Simply insert the name of a hotel in your area and either print out information on the hotel (or provide a QR code if your students can use their smartphones in lessons). You will also need to provide the students with a menu from this hotel (or cheat and use one from a different hotel).
Of course, you can adapt this to be a written exercise as the students could write an email reply for each query. If you want to make the exercise a little more challenging, record the queries as an audio file in the form of a voice message from the sick colleague. That way you can practise listening skills and get the students to write down the information for each query.
