Travel and Tourism Industry in USA?

I'm interested in pursuing a career in the Travel and Tourism Industry. I am wondering what state or city in the USA has a really good Travel and Tourism industry. It would be great if you could help.
And reccomend Cities throughout the USA that has great Tourism Industries and what types of jobs and what qualifications I would need.

Im not exactly set on being a Flight Attendant but it interests me so what would be the best place for that and what degrees etc. do you need to have in the USA to become a Flight Attendant or any other jobs in the that industry.

I'm definately not planning on going into the industry as of yet as I am still in school and quite far off from finishing and Yes, I understand that you need to be a citizen etc. and it would be awesome if you could give me some advice on this.

Thanks so much!

Dallas , Texas has a huge amount of Air Traffic and Flight attendants .

Orlando , Florida , has quite a bit of Tourism . Miami , Los Angeles and New York city have large International Travel hubs .

It's interesting. Good Luck!
