What all kinds of jobs are there where you have an expense account or travel & your room and food is comped ?

I was just wondering about this because I love staying in hotels and traveling and if I could find a job that would require me to do this I would be interested in checking it out to see if I might like it.

Pharmaceutical sales rep could be one.
Account manager is another.

You could indeed be a sales rep or account manager, or work for a International company or one which has regional operations whereby you hold a customer-facing position as usually this involves over-night travel

However I have to say it (been there, done that!) the novelty wears off very quickly. Of course (for cost reasons) you get a reasonable but not top class hotel and after a while they all start to look the same and it gets very monotonous .... airplane to taxi to office to taxi to hotel to office to airport..... etc You don't get to see much of the area unless you are able to go to dinner by yourself (although mostly you normally dine with your customers/associates)

So I would say focus on the content and area of job that you would like to do first, and then if travel is involved it's a bonus..... but if you have a job you don't like or can't perform to your best capability, the travel side of things will not compensate

Best of luck
