Hi Karen!
Thank you for visiting the Moms Panel!
If you are driving from a location off-property, outside of Walt Disney World Resort, you may need specific directions from further away, and Disney can help you with these if you call (407) 939 4636. For the Magic Kingdom you will need to take I-4 to exit 67 (westbound) or exit 62 (eastbound), then continue for approximately four miles to the toll plaza, and Magic Kingdom parking.
There are very good road signs within the Walt Disney World Resort, and it is a straightforward drive to any of the theme parks. When you arrive at the Magic Kingdom parking lot, you will be required to pay approximately $14 for all-day parking (and this pass will be valid at any of the other theme parks during the same day). Parking is free to Walt Disney World Resort hotel guests. After parking you will take a tram to the Transportation and Ticket Center, and then you have a choice of either monorail, or boat, to the theme park entrance.
The same directions apply for Disney's Hollywood Studios (I-4, exits 67 westbound, or 62 eastbound), then follow the signs for Disney's Hollywood Studios parking. The same fee applies, approximately $14 per day. When you have parked, you will take a tram to the park entrance.
