I had a look at the Cruisemapper Website - Coral Princess Port location in Dubai is stated as Port Rashid-Dubai Harbour, UAE - in the suburb/locale of DEIRA.
We are staying at Dubai Hyatt Regency Deira on Sat & Sun night so should be able to see the Ship from room or top bar of the Hotel. (Cheers!) Not exactly certain on which terminal - might find out closer to the day, or, on the day! 😀
