Hi Barbara and welcome to planDisney!
Using the various different types of complimentary 
Resort Transportation on offer at 
Walt Disney World is something that my family really enjoy doing during each and every visit. There's just something about listening to the pre-recorded safety instructions, whilst headed to a Theme Park, which is weirdly comforting. Obviously, it goes without saying that there's nowhere else on Earth I look forward to being told to "stand clear of the doors" or to "remain seated while the motor coach is in motion".
The 
Walt Disney World Bus Service typically starts running park-to-park buses at around 10:00 AM, although specific start times can vary. 
Top Tip - The "Get Directions" section of the 
My Disney Experience Mobile App will come in really handy when trying to work out the best way to get from one place to another. The most direct route may involve a combination of bus, monorail, boat, 
Disney Skyliner, or walking. 
If you are unsure at all, please ask a Cast Member who will be more than happy to assist you.
I hope that this information has been of use, Barbara. Please feel free to re-visit us, here at planDisney, if we can be of any further help with the planning of your trip.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
