If you want my opinion I wouldn't bother! I teach travel and tourism and it is nowhere near as worthwhile or rewarding as you think! Its hard work, often the students think it is an easy option with dreams of being a rep on one long holiday! The paperwork and legislation limits your teaching to a massive extent and the PGCE is a waste of time! At the moment teaching jobs are very scarce due to the credit crunch, I have recently left mine to go back into the industry as it was far too stressful, same thing every day and left me feeling very disillusioned! Get more experience in industry and re-think it in a few years time!
