How long does each presentation have to be?

All lectures should be 45mins and leave the stage on time and accompanied by a quality powerpoint presentation. Q & A is not suited to cruise ships, although this may be suggested by the CD who would arrange this and make the necessary arrangements. Lecturers usually say to guests that they are happy answer questions in a certain lounge or area after the lecture. It is very important not to run over time, as this may affect your feedback.
