Going to Disney World to visit my cousin. He has an AP, I have a one day park ticket already attached to my MDE. We each have park reservations for HS. We both plan to purchase Genie Plus for that one day. I want to add him to my MDE because I will be handling LL reservations. In the past I had my kids and their tickets and passes on my MDE. Is the process the same to add my cousin to my MDE? Is it different because he is an AP holder?
