Hotel / Hospitality Management

Hi Mohan,
Firstly, I would suggest you to know yourself, which means, your own interest areas, your skills, knowledge and willingness for the subjects. This will let you know which field will help you in getting better results.
As far as MBA in finance is considered, if you have good knowledge about basic accountancy, cost accounting and financial management, you can go for it or even if you have knowledge about accountancy, even then it will work.
For MBA in Hotel Management, you should have better command over management, business skills and communication along with organisational behavior, so that you can have a better output at it. But even if you have some good level of knowledge about business studies and management skills, you can opt for it.
Rest, I will suggest you to do what you're good at.
Good Luck.
