Hi Amy,
I hope I've caught you before your trip!
The Caribbean Beach Resort is pretty centrally located so it doesn't take too long to get to any of the parks from there. Here are the approximate times -
Magic Kingdom - 20 minutes
Epcot - 15 minutes
Disney's Hollywood Studios - 12 minutes
Disney's Animal Kingdom - 20 minutes
Blizzard Beach - 13 minutes
Typhoon Lagoon - 19 minutes
Downtown Disney - 25 minutes
You also need to allow extra time to wait for the buses to arrive. I like to use the Transport Wizard which can be found at the bottom of the main page of the website
www.ourlaughingplace.com to help me plan my trips around WDW.
Have a great trip,
Jo
