if anyone ever wanted the description of 'Evil Corporation' These Cruise companies fit the bill pretty damn well. They are foreign operations operating foreign flag ships with crews of foreign nationals. Shore-side they own the majority of those 'mom and pop' trinket shops outright and what they don't own they charge massive marketing fees to or very carefully divert their passengers from the store. 

The labor they use both ashore and afloat is unbelievably cheap, minimum wage students shore-side and pennies a day foreign nationals in the ships. 

Come the end of season all the shops close and the 'workers' migrate to southern ports  and into stores of the same name as the one they just closed for the season and resume selling the exact same trinkets and polished rocks. 

Meanwhile, the only thing routinely left behind are demands for 'improvements' at the ports and in the tourist district and threats to file law suits if any head tax money ever gets used more away from the beach.
