Do Hotel Managers Travel alot on business?

What are the positive things about that career

No not really

At the "Unit manager" level, most companies will have you travel once or twice per year for managers' meetings where your immediate supervisor and his other managers discuss goals and business in general. That's usually "same day" travel or just a weekend or so.

You may also get some training initially and periodically thereafter that will require being away for a week or longer.

Otherwise, your job is to manage a hotel which, I assume, doesn't move around much. The next level or two up is where you start travelling a lot. At the District or Regional manager levels, I mean, where you're supervising (typically) 6-12 hotel managers.

No they stay in their hotels and manage them. be prepare to be married to your job if you want to be the best.
Being a hotel manager means you can do any job in the hotel if someone is sick and you must get it done right.
Being a hotel manager means knowing who to delegate authority to so everything goes off without a hitch.
Being a hotel manager means being able to talk to any group of guests and make them feel at home and make all their problems disappear without loosing your cool or breaking your budget.
Being a hotel manager means knowing how to keep most of your employees somewhat happy and somewhat busy so they don't become disgruntled or bored but still have time willingness and energy to pick up the pace when the business is good and pay their bills when business is bad.
Being a hotel manager means knowing when to let someone go if they are not pulling their weight and knowing how to carry them when they can be redeemed or firing them would leave you shorthanded.
Still like the job?
Go to a good junior college or vocational school and within two years you can be in the industry and after a few years of working for others if you are diligent you can be the hotel manager.
If you don't like it don't waste your time or theirs.
