Given that you are London based, the term 'dissertation' usually deals with an honours degree or a masters...advice can be pretty scant for honours and some masters programs in London, depending upon your degree program and the university....making an appointment with your adviser is still the best bet......

However, you have provided few details as to your course of study and little idea as to what aspect of business travel or luxury hotels you are investigating. Depending upon your course of study and the aspect you have chosen, I could perhaps assist.....but I (we) need to know more.....

Please send a PM with any details or questions, if you wish and welcome to FT.....
