So I'm heading to WDW in January and was looking to link my sister to the Dining Reservations. We both have accounts, but she has not added the rest of her family members to her account. I can't simply add her to the dining reservation, I need to make sure everyone else is accounted for as well. We have other people joining us that don't have accounts. Yes, I could create usernames for people under me, but that's annoying as well.
To clarify, this is what I'm doing. I have a reservation for 10. I want to modify the guests going to the reservation. Right now the reservation shows up as myself and 9 guests. I can add my sister as 1 of the 9 guests on the "modify guests" page, but it won't accept just the addition of her. I need to add the other 8 guests in order for it to be retained. The annoyance here is that you're not required to have all members of the party identified, and the only reason to link it is so that people that are "controlling" the vacation can see it on the app. It's designed in such a way that it won't let you do that.
I decided to take this up with Disney, and in just over 20 minutes I was fortunate enough to get a person on the line. The person saw the issue and agreed with me that the current set up isn't beneficial. There were no real workarounds should of creating a bunch of dummy names to fill out the rest of the names.
I also love the last question of their surveys.
Which of the following best describes your call experience today?
