The person with the ticket can make reservations 30 days in advance. The person without a ticket will not be able to make reservations in advance. Once there, when the ticket is added to MDE, you may be able to get the same FP times for the new ticket, but that is entirely dependent upon whether or not there is still availability at the specific time for the attraction. It works the same as it does if I try the same thing today- I can try to copy my A&E and 7DMT to my husband, but if there are no open slots I won't be able to do it.
