I don't believe that Four Seasons owners get an AC for depositing weeks into II. I believe this is the same for Hyatt owners as well. The contracts that II has with both Four Seasons and Hyatt do not provide for ACs to be granted. It may be because both of these companies control the weeks that are deposited to II rather than allowing the individual owners to reserve a week and then deposit it. I'm not certain. I'm a Four Seasons owner and, like Bill suggested, I never deposit my Four Seasons week with II.
