I don't know if you got an answer but with your ticket party, you have access to the Disneyland Park at 5p.m.
You don't need an other ticket. But if you want to visit the Parks during the day, in this case you need a ticket.
I hope I could help you even if you asked your question 4 months ago xD
Sorry for my english :/
Your pictures are gorgeous :3 !! You're a perfect Tinker Bell !
