Hi Denise! How exciting that your first trip to Disney World is almost here! I think that once you arrive at Disney, you'll find that getting around is a snap! Disney has a great transportation system that's easy to use.
From the Magic Kingdom, you can either walk or take the monorail to the Contemporary Resort for your dinner at Chef Mickey's. The trip will take about 10 minutes, or less. To reach the Boardwalk from the Hollywood Studios park, just hop on the boat and you'll be there in about 25 minutes. When you leave the Animal Kingdom, just take the Wilderness Lodge bus to get to the Whispering Canyon Cafe, a trip that will also take about 25 minutes. You may have to wait 10 to 15 minutes for buses, boats and monorails to arrive, so be sure to budget a little extra time for waiting.
I think you would find the Transportation Wizard on the website
www.ourlaugingplace.com helpful -- it gives you options and travel times for getting around on Disney property.
Hope this helps! Come visit us again if you have more questions! Have a magical first visit to Disney World!
