Platinum priority embarkment

We are platinum but traveling with my MIL and SIL who are silver but our reservations are linked together. Does anyone know if they will let them board/check in with us since it is not VIP just priority after suites? They did get assigned the earliest 9:30 check in time like we did

I only found this about platinum priority - we are leaving out of Miami if it makes a difference

At each embarkation port there will be an exclusive check in line for Platinum, Platinum Plus and Ambassador members. We ask that eligible members check in through this line. After check in, Platinum, Platinum Plus and Ambassador members will be guided from the exclusive check in line to a priority embarkation seating area. Once the ship is ready for priority embarkation, Platinum, Platinum Plus and Ambassador members will be invited to board. Priority embarkation will take place immediately following the completion of embarkation for guests who require special assistance and The Haven™/Suites guests. Members who check in once embarkation has already commenced will follow the same process, however priority embarkation once boarding has begun cannot be guaranteed at every port; members may have to board in order of arrival at the port. The priority embarkation seating area may not be available at all embarkation ports. Priority embarkation may not be available at all embarkation ports.

If you have a 9:30 check in you will all probably be able to board relatively quickly after they begin boarding, which might not be until after 11:00. Sit and chat, enjoy your time together and board when your MIL' s zone number is called.

They will probably not be able to sit in the special area with you since someone at the door to that area checks to make sure of eligibility. If they are not allowed to sit with you, no way to board with you. So it is going to depend on the person allowing entrance to the separate seating area.
