Arrive at least the day before. Move in is that Monday, your CP will be assigned a move in time, should be sometime between 8-11am. She will get in line to check-in, get a pic taken for her ID (should follow Disney look book from shoulders up), get her apartment key/room/bed assignment. The community centers have a video playing for parents to watch while waiting. At some point that day she'll have a background check. There is also a 1 hr class on how to make the most of your program. When moving in, allow your daughter to go into apt by herself first to see if other roommates are sleeping or getting ready for work. You should not be in the apartment without her.
By Tuesday she should be given a 3 day park hopper ticket to use for herself within a week. Usually, first paid training is Friday/Saturday (Traditions parts 1/2). But, depending upon role, that Wed/Thur, they might have lifeguard training/testing or the POET test to see if they can physically accomplish their role (usually for custodial.). My DD was quick service and had food and beverage training the Sunday after traditions, then park orientation Monday, then role training after that. The Friday/Sat/Sun training was at Flamingo Crossings East, about 4 hrs/day.
Our DD was a CP from 1/8/24-1/9/25. We arrived the Sat before (partly because it's winter and we're coming from MA), We all had annual passes, so we did a park Sunday, move in Monday (took forever as she was in the biggest move in group they ever had, over 2000 people.) We had time to go shopping for cleaning supplies/groceries before her background check. Tuesday we met her at a park (she took FCV bus to practice) and said goodbye from there (worked well, not as emotional as move in day) then we flew home Wednesday afternoon. That worked well for us, we wanted to be there Tuesday in case more shopping was needed as she doesn't have a car. We flew Southwest, the 2 free checked bags each was great for moving.
And Congrats!
