My DD moved in back on Monday June 9. She had her 3 day park hopper by the end of move in day. Traditions was Friday but she did not receive her self admit pass for about two weeks as did her other roommates. I believe two weeks is the norm for the self admit pass as one roommate moved in about 1-2 weeks before her and got her pass the week DD moved in.
She used her passes to hang out with roommates, make friends and go to the parks with them. I went home Tuesday afternoon after moving her in Monday. This is something we discussed before going down. She wanted to hang out with me Tuesday since I had a later flight but I really pushed for her to make friends and start her new journey. It really worked out well for her.
