Booking FP+ for our off site friends

Before the 60 days FP window opens I want to make sure I have this right. We are staying on site and want to book FP for us and our friends that are off site. I entered their names in my ‘friends list’ manually.
Is this all I have to do in order to book their FP 60 days out? (They will be going on all the same rides at the same time as us)

I don’t think that you can book for them just because you have added them to your Friends List - I think that they actually have to have an on-site reservation as well.

I think this used to work but I have read two reports in the last two weeks that it did not.
