Tourism is, of course, a major employer/money earner in the UK and ranges in scale from day trips to lengthy holidays here. This led me to wonder what would your characters in your stories do when they wanted a break from the routine. What form does tourism take in your fictional world? Is it a case of most people never travelling anywhere (so strangers in town really do stand out)? Or does your world encourage people to visit other places (to colonise, to encourage good relations between different species or because it too wants to earn money?!).
How do your characters earn money from tourism? Do others, not directly involved with the industry, resent visitors or welcome them? And where magic is involved, how does that affect the tourist trade (it could be based around magical artefacts and places to visit for one thing)?
