Hi Jamie:
Try the following: Head to the
Walt Disney World Resort page and hover on the "My Disney Vacation" button next to the small orange suitcase icon on a top menu. A drop down menu should appear, including an option for "Online Check In."
The big benefit to on-line check is that it can help speed up the check-in process at Disney Resorts. When you check-in on-line before arriving at the Resort, you provide your party's names, address, contact information, any room requests (based on availability), and a credit card for room charges.
When you arrive at the Resort, you will look for the signs directing you to on-line check-in at the front desk. You will have to wait on line, if there is one, to pick up your welcome folder and Key to the World card (your room key with charging privileges), but theoretically, the line, if any, and the check-in process should move quickly since information was already provided during the on-line check-in process beforehand.
Enjoy your vacation.
