Earlier I posted the Twitter conversation with WDWToday where they told me I’d be able to register my 2 boys age 11 and 14 under my
MDE account... to follow up I just called VIPassholder support. They told me that because my children are under 18 and Platinum passholders I would be able to register them and they did not recommend that I create a MDE account for my 14 year old. They also told me that I would be able to choose the lightsaber experience for them and the Cantina for me.
The cast-member also told me that they expect to find out the morning that the email is being sent out (as little notice as an hour before) and as of right now they hadn’t been told anything. I hope this helps give some clarity. I know that there has been a lot of conflicting information out there, but the information that I received from Disney on Twitter and from VIPassholder support has been consistent.
