Hello,

You are doing diploma in mechanical engineering. Which is great.. After completing your diploma you can get lateral entry in 2nd year BTech in engineering colleges. But you don't want to pursue engineering I guess.

So yes you can join hotel management course. Hotel management have 2 types course one is for three years and another one is for four years. You have to choose which course you want and take admission. But in hotel management you have to study from 1st year.

All the best.
