1. She can only make FP+ reservations after she buys tickets. If she waits to buy her tickets until she is at WDW, she can make FP+ reservations via a smart phone (or other connected device) or make the FP+ reservations in the park(s) via the FP+ kiosks. If she has not already done so, can set up her own
MDE account now, if she likes, and be ready. 2. MDE accounts are not related to specific trips. MDE accounts are connected to individual GUESTS and can span any number of trips and any number of tickets.
