There is no such restriction. You can still opt this course. My friend is a pure vegetarian and he is in his 2nd year of BHM course, yet he has not eaten non-veg, no one would force you to consume meat. The field is vast, so don't worry. The right choice is made, just go for it. You have a beautiful life ahead.

A degree in travel and tourism management prepares graduates for careers as travel agents, lodging managers or meeting, convention and event planners.

You will have to check the website. I am not pretty sure about the Diploma, but most probably, yes.
