Ahoy there, Kimberly! Welcome aboard planDisney!
Looks like you're planning on
starting 2023 off with a Disney Cruise Line vacation - now that's what I call a magical way to kick off the year! Hard act to follow for the rest of the year, though!
In any case, looks like you also took the planDrew-approved approach of booking multiple staterooms on a single reservation! That simplifies things so much from a linking perspective, making planning
Port Adventures and onboard fun even easier! It sounds like you may be wanting to reassign some Guests - perhaps to take advantage of
Castaway Club status in each stateroom? You're hitting the trifecta of things I'd do myself!
Now, while you can
modify reservations online in the "my reservations" area of the site, this capability is more helpful when making changes to your stateroom. Whether you're looking to upgrade to a higher stateroom category or just feel like changing your location around the ship, those types of changes are easily done (subject to availability). As to why it's asking you to first remove a Guest - once you've placed a specific number of Guests in a stateroom - even if it's below the room's maximum capacity - the system won't allow you to add a Guest, since your reservation is for a set number of Guests!
Yeesh, I sound like Captain Jack Sparrow explaining to Mr. Gibbs why he woke him up...
Oh, and there's the additional question of whether your reservation is one with restrictions or not! If the reservation has restrictions, most are non-transferable and non-refundable, and the same goes for Concierge level accommodations.
Because of all that fine print, whenever I want to make a change or rearrange stateroom Guest assignments,
I always contact a crew member by phone. When last I spoke to the crew, they reminded me that if the name change is 45 days or more prior to your sailing, then there will be no charge associated with this update. Of course, Disney Cruise Line reserves the right to restrict any changes to a reservation, and all changes are subject to availability. I hate to quote Scar, but when it comes to making changes, "Be Prepared" and do so as early as possible - which you're obviously doing!
I hope that helps point your compass in the right direction as you continue planning, Kimberly, and thank you for your question! While your sailing is still a bit far off on the horizon, if you have any additional questions as you DREAM up the FANTASY you hope to experience on your family's adventure, please sail my way again here at planDisney! I'll whip up whatever MAGIC I can to ensure you don't WONDER what other plans you should make! No need to use your three WISHes!
SEA ya real soon!
