Syden-turist is the way to break up the word.

It implies 'sun-hungry' - tourists to southern climes, people who just can't wait for the spring at this time of year after the murky northern winter. Those who can afford it take a break in a warmer climate further south.

Charter tourists are what many of them are, even if it sounds slightly more mundane.

I did not see the question until after you had presumably sent in your assignment, so I have no qualms about answering. Best of luck with it!
