Not true. You have to stay on site and have a ticket to link. I have AP amid my dad was going to order through
undercover tourist. Even though he was staying on site, he couldn't schedule fP+ because it was insisting on linking a ticket first.
And we are Dvc. Sometimes we have a AP, sometimes it runs out and we wait Gil we get there to buy again. The renew discount isn't great enough for us to buy and let sit unused. So on the years we need to buy there, we'll need to use kiosk.
Whole thing sucks. Last trip in Dec, we waited 35 min while people were making changes.
MDE was so overloaded, we could barely pull up wait times, let alone make changes. We've already decided next trip will be Universal, Legoland, sea world etc... They are just making it too much work. We like to relax and just go where the road takes us....
