Make sure she is listed on your reservation and then linked in
MDE. If she is not, then she will have to "pull" from the AP bucket of reservations and make them, as
@Dave006 mentioned. If she is on your reservation and all her information matches her AP (age/name) and you are connected so the reservation shows on her MDE account, she should not have to make reservations since it is not required for resort guests. If issues, the CM at the tap styles should be able to fix it if she shows them her MDE account. She could always make them to avoid any problems.
