Castaway Club is Disney's multi-tiered loyalty program for past passengers. It has only three levels, based on number of cruises sailed, and doesn't offer quite as many perks as many of the other cruise lines. However, if you're a Disney devotee, you'll benefit from the extra perks.
Once you have completed your first cruise, you are automatically a loyalty program member. Levels are achieved based on how many Disney cruises you have taken, rather than how many days you have sailed or how many points you've earned through onboard spending. That means that you can level up fairly quickly even if you only ever take short cruises.
All Castaway Club members receive special booking offers and in-room amenities not offered for purchase; Gold and Platinum members also receive additional merchandise discounts, the ability to book cruises before the general public and more. If you share a cabin with other Castaway Club members of different levels, any in-cabin benefits will reflect the highest status of all the passengers in the room.
Disney ships sail full all the time; very few dates are offered at a discount. However, loyalty program members do receive exclusive discounts on select merchandise.
