For those that suggested I emailed. I got this reply. Still no idea if I am "eligable" and what that means but I've updated my settings so fingers crossed though still can't access at this stage.
To ensure that your booking qualifies for this program at least one guest must be opted in for our promotional emails. To confirm this, please log in to your account and check your email preferences or call the Captain’s Club at 800-760-0654. You will be notified of the program details within 21 days to sailing via email.
Please note that some offers may be sent inside the 21 day window and are not guaranteed for every reservation. All Moveup communication will be sent to the email you have on file as long as the guest is opted in for promotional emails. The Moveup tool on the consumer website will continue to prompt this message until an offer is sent to you via email if your booking is selected.
