I got through at about 7:30am Central, after having many issues even getting the "Request Live Chat" button to activate. The chat and video call took about 40 minutes! The cast member was super nice, however, she was learning the process also, and some of the screens on her end weren't loading properly. She had to mute me at one point and received assistance from a colleague. My trip is next week, 10/20--10/24. I now have two advanced
DAS reservations for each of the four days of my park reservations (10/21--10/24). Pleased overall.
