FYI, if you have booked and want to modify your reservation at all, you can’t call to do so until after October 28. And you are best to phone the Starcruiser line, not the general reservations one. The regular reservation team is not allowed to even access Starcruiser reservation and the SC team won’t be doing it until after the bookings open to the general public, according to the CM I talked to after a 2 hour hold…
(wanted to give Disney more $ and upgrade to a suite, but can’t even discuss availability at this point)
