Hi there, Jennifer!
Walt Disney World Resort transportation can definitely enhance a vacation -- and I am glad you are figuring out routes and timing early for ease of managing your itinerary.
Because I'm not sure of the time of your reservation at
1900 Park Fare, I'll make the assumption that you're eating and heading straight over to
Disney's Polynesian Resort for fireworks. And please feel free to drop me a line to offer any more details you'd like - or correct my projections!
From
Disney's Caribbean Beach Resort, you'll need to hop a bus to either Magic Kingdom or Epcot. When you have arrived at the Park, simply access the Resort Monorail (not the Express, which skips the Resorts and heads right for the Ticket and Transportation Center) and get off at
Disney's Grand Floridian Resort and Spa.
When your meal is over, you'll head right back to the Resort monorail and enjoy a short ride to the Polynesian for fireworks.
After the nighttime spectacular, you'll hop the monorail again, heading back to the theme Parks, at which point you'll need to catch the bus bound for your Resort. Bear in mind, please, that transportation from the theme Parks runs for an hour after the Park closes.
Have a great - and well-planned! - time!
See you later, celebrator,
-Deborah B.
