Hi Connie!
Thank you for visiting the Moms Panel!
There are early morning buses available to take guests to their early morning destinations.
Buses will begin arriving resorts at 6:30 a.m., however if you've been waiting an extra long time, feel free to call Bus Operation Center directly at 407-824-7092 and let them know that you need immediate transportation. You may wish to check with your resort front desk about where to wait for your bus, but I would recommend that you are ready to take the first available bus, so that you arrive at your breakfast reservation in comfortable time, at both Disney's Polynesian Resort ('Ohana) and Disney's Beach Club Resort (Cape May Cafe).
You can reach the Magic Kingdom park by boat from: Disney's Grand Floridian Resort & Spa, Disney's Contemporary Resort; Disney's Polynesian Resort, Disney's Wilderness Lodge Resort, Disney's Fort Wilderness Resort, and from the Magic Kingdom parking lot at the Transportation and Ticket Center.
Both Epcot and Disney's Hollywood Studios can be reached by boat from Disney's Yacht & Beach Club Resorts, and Disney's BoardWalk Resort, and the Walt Disney World Swan and Dolphin Resorts.
From Downtown Disney you can only take a boat to three resorts: Disney's Saratoga Springs Resort & Spa, Disney's Port Orleans Resort and Disney's Old Key West Resort, then transfer to a bus to a theme park.
Walt Disney World Resort Transportation is outlined in more detail
here.
If you have any other questions, please come back and ask me - I would be happy to help you plan your magical vacation!
