If you have a pack mule, pack all your wine and soda for both cruises on the first embarkation. Have all documents available for security, if necessary.
You will be able to get whatever dinner reservations you want for the second cruise as you will have easy access to the staff.
Leave the ship early on the first disembarkation and go enjoy the city for the day (return at 2:22pm), accidentally forget the wine and soda that you brought on the first embarkation and bring an additional supply.
🙂
Wash you clothes on the latest day of the first cruise allowed or on day one of the second cruise.
If you are changing loyalty status between the two cruises, talk with the loyalty staff during the first cruise.
