Hi Gregory! Welcome to planDisney!
It looks like today is the big day! I bet you are busy packing and 
completing your to-do list as you prepare to travel to the Most Magical Place on Earth. It will all be worth it very soon when you are enjoying the 
Walt Disney World Resort 50th anniversary celebration!
I think you may be referring to 
Online Check-In for your 
Disney Resorts Collection hotel reservation. If so, I am happy to say that you are welcome to complete Online Check-In to get a head start on enjoying your vacation. You'll be able to choose room preference, credit card information, arrival time, and more.
If you include your mobile phone number during Online Check-In, you can receive a text message when your room is ready and it will include your room number, plus a map of your resort. No need to stop by the Front Desk! Once you have received the text message, simply head to your room and use your 
MagicBand or the 
My Disney Experience mobile app to open your door.
I hope you have the BEST vacation, Gregory! Please let us know if you have any other questions.
Tabitha
