Welcome, Sab! A back-to-back vacation sounds practically perfect to me, especially onboard one of the
beautiful ships in the
Disney Cruise Line fleet.
The
Castaway Club, the Disney Cruise Line loyalty program for return cruisers, has some really awesome perks. You've mentioned the booking windows, as the higher level you are in the Castaway Club, the earlier in the process you can book
onboard activities and
port adventures. It's a club worth getting into, for sure.
You become a
Silver Member of the Castaway Club upon completion of your first Disney Cruise Line cruise. You will be a Silver Member as soon as the first leg of your back-to-back cruising is finished, but not in time to get the booking advantage on this particular sailing.
Sab, if you end up moving in this direction, before you disembark the ship between sailings, head down to Guest Services onboard the ship just to give them a heads up about your leap in status to Silver Castaway Club member. There may be a Silver Club member surprise waiting for you upon your return to your stateroom, but because it can take a few days to update your status in the computer, it may not be an automatic transition with your Silver level benefits.
I'm so glad you visited us with this question, and I hope you'll visit us again as you draw closer to your incredible high-seas adventure.
