Oasis of the seas and Allure of the seas coming out within a year of each other seems like too much to me. It's the economy right now. I remeber NCL putting these 3 ships in Hawaii and it felt like over expansion in that market. Sure enough 2 of the ships were moved out of Hawaii.
RCL is flooding the Caribbean market. One of two things will happen RCL will move one ship either Oasis, Allure, Liberty and/or Freedom out of that market. Or it will squeeze out the other cruiselines and RCL will have a monopoly of the Caribbean market. I don't think the monopoly will happen, Carnival is to much of a value to be driven out. This will be interesting to watch.
I'm not against Oasis of the seas I would love to cruise on her. However, I'm looking at it from a business point of view. I think they should have released the Oasis of the seas and held off on Allure or put Allure in another market. Now if they could add Cuba to the list of ports this might change things.
