This is a very commonly asked question and there are a couple of things to consider. First, if you need an accessible room, book as early as possible. These adapted rooms are extremely limited and sell out quickly on popular itineraries.

Second, if you have a preference for the type of cabin or its location, you should also book early for the best selection. Finally, if you are looking to catch the best price, either book when itineraries are first released or within 3 months of the sailing date.
