Typically a bachelors degree is 4 years, but you could do it in 3, some colleges offer fast track programs. I have never really heard of a 1 year bachelors degree.

As for the hotel industry if you want to be a manager, then look at business management or administration degrees, an HR degree would be good if you wanted to specialize in hospiltality human resources.

Hospitality is a good field to work in, but jobs are competitive, with most hotels, restaurants, and other hospitality enties often promoting from within. Normally these jobs can mean long hours and requring a great deal of customer service skills. If you are looking to get into the field, I suggest securing employment or interning at a restaurant, hotel, country club, or some other type of hospitality entity.
