I like everyone's wish list for the new itinerary. I am on the full World Cruise BTW.
The reality, as I see it, is Crystal will follow Carnival Corp in rerouting around Africa. Flying and hotels would be extremely expensive and more disruptive. In addition Serenity and it's crew are too valuable to risk in the Red Sea.
I would believe most of us are on for the hotel,food, entertainment, service with the itinerary a close fifth.
Going around Africa non stop would only take at about 10 days. Planned from Perth to Limassol 30 days.
I don't expect any announcements until ports are selected and all logistics finalized. Life should have surprises and wonderment.
