The economic value of cruise-ships is on full-display as the season draws to a close. 

They've brought in 350,000 visitors, with an estimated value of $540 million. 

Newmarket Business Association Chief Executive Mark Knoff-Thomas told Francesca Rudkin they've seen a 30% rise in international visitor spending this season. 

But the bounce-back may be short-lived, a 20% decline in port visits is projected for next season as rising costs bite the market.
