Hi Amber,
Actually, the fun pirate themed rooms at the
Caribbean Beach Resort are some of the furthest away from the Old Port Royale. There you will find dining, a lounge, shopping, the main pool and more. To be close to the main area, you would want to choose a "preferred room" instead of a pirate one. Rest assured that an internal shuttle is available to get you around the expansive resort.
Since you booked through the Disney website, I recommend that you call a Travel Planner at 407-939-7675. You are able to change your reservation to a different resort, based on availability, without charge if this is what you choose to do.
Hope this helps and have a wonderful vacation. Let me know if I can help you further,
Kaylene
