Coming Soon: 2 Exciting New Features
These options will be available in addition to our existing, in-person DAS program.

Pre-Arrival Registration and Planning via Live Video Chat
This fall, we’re introducing a new option to register virtually with a Cast Member via live video chat as early as 30 days in advance of a park visit.

During your chat with a Cast Member, you’ll also have the opportunity to select up to 2 experiences per day (subject to availability) using our new DAS Advance planning option. Please keep in mind that DAS Advance selections must be booked at least 2 days prior to the day you plan to redeem them, and you will not be able to make selections on the day of your visit.

If the experience you want is available, you’ll be given a one-hour return window to redeem during the day of your visit. Any selections you make will appear as plans on the My Disney Experience app or on this website.

Please note: at this time, live chat will be offered in English only.

Same-Day DAS Return Time Self-Selection Tool
A new way to request return times is also debuting this fall. In lieu of having to physically go to an experience or to a kiosk to obtain a return time from a Cast Member, Guests registered in the DAS program (and their party members) will be able to make return time selections right from the My Disney Experience app during the day of a park visit.

Stay tuned for more details!
