Allure of the Seas Itineraries Announced March 31, 2009Royal Caribbean announced today Allure of the seas (sister ship to Oasis)itineraries. Nothing really big here. It’s the same as Oasis, sailing Eastern and Western Caribbean. The big difference; Sunday Departures. Allure will also sail from Port Everglades and needs to use the massive new terminal. Obviously, both ships can’t dock at the same time so they leave on different days.
