Hello,

A career in tourism may not sound like a sound option if you are looking for job security or a high pay. On the other hand, if you have an interest in the stream, then it is worth pursuing regardless of the practical implications, because sometimes such nonconventional careers do pay off; for around 10% of the graduates in the stream. In such a case, it would be best to pursue a degree program in hospitality and tourism in order to increase your job prospects as well as your qualification in the same.

If instead, you have no inherent interest in tourism and simply want to see if you would be comfortable with a career in it, then a diploma is the cheaper option, although personally, I wouldn't opt for a diploma option unless it is at one of the top universities for hospitality in the country i.e. IHM. Therefore, a diploma in tourism would truly be worth doing only from one of the best universities in the country. 

Additionally, if you wish to pursue a program in tourism abroad, then you are bound to get a higher salary as well as a larger pool of job opportunities to choose from. Therefore, it is best not to take rash decisions until you know exactly whether you want to pursue a career in tourism or not.
