When my daughter lived in Europe, she worked for one of the outdoor adventure travel companies.
Even though she enjoyed the job, she said it was a lot of hard work. Just leading the adventures kept her in pretty good shape, but there were many people who showed up and didn't have a clue what they were doing.
Not only was she responsible for keeping everybody safe, but also that they had a good time. After a couple years of this, I think she had enough adventure for awhile and was ready to look for something else.
It was a perfect job for her when she was young and single. I know that there were many people who were able to have a unique adventure and lasting memory because of what she did.
She isn't as interested in hiking and camping as she used to be, and now wants to go on a cruise and just relax for a good vacation.
