You probably misunderstood and/or just assumed when posts said guests could be linked to more than one DAS holder, that it also included the DAS holder.
You might also have read misinformation somewhere else. People on disABILITIES Board have always been clear in explaining the DAS HOLDER can only be on their own DAS. But, I just read a posting on a Facebook page that “you’re lucky you have 2 people with DAS because you’ll be able to double up” on DAS Return Times. The person who posted that had not used DAS - that’s not how it works.
As for the DAS Advance Selections, each DAS HOLDER will need to make their own when they do DAS video registration. Since the additional guests can only have one DAS Return Time, you’ll need to decide ahead of time who will be on which DAS Advance Selection.
Also, if both DAS Holders have THEIR OWN My Disney Experience (
MDE) account and are planning for themselves, it’s possible only one of them will be able to make DAS Return Times for the entire group. Friends and Family will be additional profiles on the MDE, but I think can only have one person designated to make plans for them. We’ve only dealt with DAS on one MDE account. Hopefully someone else with 2 with their own accounts can verify how it works.
