Cool puzzle to figure out! Probably not a 'right' answer....but...
Here's a plan that gets to all the premium resorts, minimizes busses, and could earn you a cool t-shirt if you make it!
Disney Springs, start
Take Bus to Grand Floridian. Tour the resort. Go through security and board the monorail. Get off at the Magic Kingdom.
Take the Red Launch boat to Wilderness Lodge.
Take the Red Launch boat back to Magic Kingdom.
Take the monorail to Contemporary Resort. Tour the Resort...mainly just the Grand Canyon Concourse. Might be lunch time by then...
Take the monorail to Transportation and Ticket Center. Walk a short distance and visit the Polynesian. Get Dole Whip. (If you're already worn out just go to Trader Sam's and call it a day...
Take bus from Polynesian to Hollywood Studios.
Get off the bus and walk over to the boat launch.
Take the boat and make stops at Disney's Boardwalk Villas, Disney's Beach Club Villas, Disney's Yacht Club Resort, and the Swan and Dolphin Hotels. In some areas you can walk along the boardwalk or walkways between the resorts/hotels...feel free to snack and shop along the way.
When you're done seeing what you want to see...take the boat back to Hollywood Studios.
Next, take the Skyliner to visit Disney's Caribbean Beach Resort, Disney's Art of Animation Resort, and the new Disney's Riviera Resort. If you'd like to just "see" EPCOT...you could do a round trip over to the International Gateway and then come right back to The Riviera.
Ok...next up...take the bus from the Riviera to....the Animal Kingdom. Hop off the bus and transfer to a bus to the Animal Kingdom Lodge. Enjoy the sights and take a look at some of the animals.
If you've done all of this...you deserve a break to wrap up the day...either something at Animal Kingdom Lodge...or...
Catch the bus back to Disney Springs to enjoy the rest of your evening there.
PS: For extra credit, when you come back from Wilderness Lodge you could switch and take a Green boat over to Fort Wilderness and visit the newly remodeled stables...then back to Magic Kingdom to continue the plan. And one other thought...confirm what time busses start running from Disney Springs...it won't be first thing in the morning...but later...probably around 1000.
Hope this gives you a place to start. Wear comfortable shoes... Let us know what you do!
