You don't always dock with the same side of the ship facing the port. (Despite the left side of the ship being called the Port side) So it truly doesn't matter which side of the ship you are on. BUT, the oceanview room you describe may very well be a porthole window. This may be a category of oceanview cabin that is less expensive than others. Your travel agent SHOULD be able to move you unless you are not willing to pay more (as a better category room will cost more money) If he won't help you move, I'd take my business elsewhere. But if he can't move you for the same fare, then understand that may be because that cabin is the least expensive category of ocean views. Ifyou offer to pay more AND your agent refuses to try to have you moved, call Carnival direct and ask one of their cruise specialists if the ship is full and tell them you are trying to move and why and they can tell you if he is being stubborn or if there just isn't any other cabins. But, don't be shocked when the CCL TA tells you that they can not re-book you... you have to go through your agent. BUt at least you will know what he is up to..
