It's been called the greatest challenge facing expedition cruising: expanding, profitably, beyond the poles. During a Seatrade Cruise Virtual session on 'Pushing the Boundaries of Expedition Cruising,' destination experts put forward an array of possibilities. They range from Lake Superior's undiscovered North Shore Inside Passage to Saudi Arabia's otherworldly UNESCO World Heritage Sites, and from the British Isles' wilderness coastlines to the Caribbean's experiential natural and cultural draws. Scenic's focus Scenic Cruises and Tours is looking at Egypt, Lebanon, Cyprus, Israel and Saudi Arabia, according to Lisa Bolton, general manager of product development. 'For us it's about the history, the archaeology and really breaking down some of those cultural barriers and allowing people to have intimate connections as humans,' she said.
