Cast members gain access to the resort discounts once they complete traditions. Your son can check availability through the HUB or the cast member reservation line. Your son can book two types of reservations- friends/family where the he isn't staying in the room with you (less of a discount) or a reservation where he is staying in the room with you (more of a discount). The discount and availability will vary. At checkin or up to one week (I believe) before checkin your son will have to show his cast member ID. Do you have a room only reservation or vacation package? Yes you can take advantage of your son's discount. However, availability with CM discounts can be limited. Have him check availability as soon as he get access to get the most options. Definitely keep your reservation for now.
Awesome. So about how much of a discount are we talking? Is it on all resorts (value, mod, deluxe)? You say more of a discount if he is staying in room. Why not just say he is? What is to stop me from having him make that type of reservation, even if he is staying in his apartment?
We have a room only reservation and have bought the 5 day PH tickets (as I don't think he will have earned enough free access passes by the time we go).
