Ahoy, Jerry!
I'm so happy you're planning to participate in the Castaway Cay 5K when you cruise in November. It's such a fun event, and a great way to tour Disney's gorgeous private island. (It's also a wonderful way to work off some of the calories from the delicious food you'll be eating on a Disney Cruise!)
The night before the run, you'll receive information about meetup times and locations in your Personal Navigator (a detailed daily schedule delivered to your stateroom). On race morning, race participants will meet in a designated location to sign in and get race bibs. All you'll be required to have with you is your Key to the World Card. Most participants choose to bring a bag with a change of clothes and their beach belongings, so they don't have to go back to the ship after the race. You'll want to maximize your time on the beautiful island!
A staff member will escort the group off the ship and to the starting point, where there will be a large box for runners to drop their gear. There are no lockers on the island, and cast members are happy to keep an eye on your belongings during the run. Once you're done, check in to receive your medal, grab your gear, and head to the restroom/changing area to freshen up and get ready for fun in the sun! What an awesome way to start the day at
Castaway Cay. Make sure to stop by the island gift shop to purchase a Castaway Cay 5K t-shirt to commemorate your race!
I hope this helps! Happy planning, and have a great run! - Diane W.
