I would like to think that you can consider starting from the hotel sales, but do sales to be very familiar with the hotel products, you can talk to them, first to the various departments to rotate, each department half a month's time, so that you will have a clearer understanding of the entire hotel action. Doing food service I worry that the actual situation and your expectations will produce too in the gap, by its state-owned hotel, if you do a year and a half and then change too waste of time.
If you have other opportunities to choose, I suggest you can consider some of the international hotels, where you will learn something more professional.
