That's true, but after reading these posts, I don't think the Journey is going to have any passengers on it either. As Peter Lanky pointed out earlier, the price of the 41 day cruise is insane (you can book the first 15 days alone for $140/night and the next 26 days at $630/night (for basically a repositioning cruise), I can't imagine anyone signing up. Also, he points out that at any reasonable speed, they can't get to Athens by May 29th. And on the Azamara web site, that 41 night cruise's itinerary says that you are "at sea" on Day 42. So I can't imagine they really plan on having guests on board.
While they haven't cancelled our sailing on the 29th, they have cancelled all the shore excursions which I'm guessing is so that they don't have to pay the vendors for a late cancellation. But they aren't ready to cancel the whole cruise yet....
Adding all that up, I think they are going to make a last minute decision to go through the Suez Canal without guests and keep the May 29th cruise (with who knows what shore excursions) or go around Africa and sail to Istanbul for the June 8th sailing....it would be nice if Azamara actually said something about their plans.
