Ahoy, Candra!
A few years ago we got our passports stamped in Nassau. I'm not sure if the process has changed since then, so you'll want to visit the Port Adventures Desk once onboard and speak to a cast member for any updated information about passport stamps.
When we exited the cruise ship in
Nassau, we went to the end of the dock and turned right. There was a tall, skinny, yellow building that housed the immigration office. We spoke to the guard at the front about having our passports stamped, and he let us enter. After that, we simply followed the directions to the Immigration Office and the Immigration Officer on duty stamped our passports for us. Easy peasy!
Please use care and caution when carrying your passports off the ship. Make sure to keep them dry, protected, and in an interior zippered pocket to protect them from theft (Disney Cruise Line recommends leaving passports, air transportation tickets and other travel documents in your room safe). When going ashore, adults are required to carry their Key To The World Card, a Driver's license, and a copy of their passport or other government-issued photo ID.
I hope this helps! Good luck - I hope you get the passport stamps you're hoping for. Let the countdown begin to your December voyage! - Diane W.
