WDW Transportation
Disney World is a great big place, and can be a bit difficult to navigate.  
Here are some tips to make it easier:

1. If you stay at a Disney owned, onsite Resort (hint, if it is called "Disney" like "Disney's Caribbean Beach Resort" it is a Disney resort...if it has "Walt Disney World" in its name, it is NOT) there is free transportation via Disney's Magical Express from the Orlando International airport and back again

2. There is no direct Resort to Resort transportation, unless the resorts happen to share transportation.  Going from, for example, Disney's Port Orleans Riverside to Disney's Polynesian Village takes a stop at a park first, if you are using Disney transportation

3. Monorail Information

4.  Some resorts have more than one bus stop, see resort Maps for locations

5. Give yourself up to 90 minutes for transportation, especially for meals, from one resort to another, or even one park to another.

6. You can't park at Magic Kingdom.  If you drive, you have to park at the Transportation and Ticket Center, and take a ferry or monorail to the park.  Buses from resorts drop off right in front of the park.  Some resorts have monorail and boat transportation as well.

7. All transportation to Animal Kingdom is by bus

8. Hollywood Studios shares a boat route with Epcot and some resorts, and is reached by bus from other locations

9. Epcot is walkable from some resorts, and is on the monorail, and shares a boat route with Hollywood Studios.  Otherwise, it is reached by bus

10. Water parks are reached by bus

11. Disney Springs is reached by bus, with a few resorts having boat routes as an option

12. Disney transportation is disability accessible
