M.Sc

Hi Sachin,
If you're asking this in the Indian context, then there's hardly any known and reputed course known as MBA in hotel management. Yes, there's an M.Sc in HM which is offered by the NCHM council. Its the same body that runs all IHMs (govt. hotel management colleges) across India.
More importantly, a Masters degree in hotel management makes hardly any sense because it adds no value to one's career growth. However, if someone wants to get a Master' degree for the sake of bolstering his/her ego, increase his/her market value in the matrimony market then I've nothing to say. Other than these reasons, I do not find any strong reason for a Masters in HM.
I'd rather suggest you get a regular MBA degree and try to get into Hotel Sales, Marketing. HR, or Finance. Yes, getting into hotel operations through an MBA, without a Bachelors in HM, is almost impossible, but so is the case with Masters/B.Sc.
Having said this, if you're talking about Master degrees in HM abroad, yes therere good prospects, but in that case, the degree has to be from one of niche foreign universities!
