Big disappointment for Royal Olympic Cruises today, which expected its newest ship, the Olympic Explorer, to be delivered from the shipyard. Olympic Explorer, the 25,000-ton, 836-passenger sister-ship to Olympic Voyager, which was launched last year, has, according to the cruise line, "technical difficulties." As a result, May 14th's inaugural – along with voyages scheduled throughout the rest of May and well into June – have been canceled. Cruisers booked on these trips are being notified as we speak – the problems were totally unexpected by Royal Olympic – and are being offered a range of options. They can book a cruise on any of Royal Olympic's other seven ships or rebook on Explorer for a later date. All those who were booked on the canceled trips will receive, in addition, a 50 percent-off discount (brochure rate) on future sailings.
