Welcome to planDisney!
It is great to hear that you already know about the
complimentary transportation services offered to Guests staying at a
Disney Resorts Collection hotel! Bus, monorail, boat, and
Disney Skyliner, the sky is the limit!
Disney’s Caribbean Beach Resort also happens to be a personal favorite of mine. The ability to combine our family's typical beach vacation with a trip to the
Walt Disney World Resort is a match made in... Orlando.
To answer your question, the
EPCOT Monorail will operate approximately 30-45 minutes before EPCOT’s opening. The hours for the theme parks have not yet been posted for the dates of your visit.
I suggest you check if Magic Kingdom and EPCOT opening times will allow for your plan. But to be clear, you are most welcome to take the
bus directly from the Caribbean Beach Resort to the Magic Kingdom and bypass the monorail ride altogether. The bus generally operates 30-45 minutes before the park also opens. If you have your heart set on the monorail, you should consider doing that to close your evening, as the EPCOT Monorail stops two (2) hours after EPCOT closes.
I hope this helps answer your question! If you have any additional Disney vacation planning questions, please come back to visit us at planDisney!
Cheers,
Brent
