I'm not sure if this is the best place for this question or not. My sister and I are going to Disney in a few weeks. I have used my MDE account for everything. My sister does not currently have her own MDE account. She wants to be able to take advantage of the mobile ordering while she is there, link a credit card to her account, etc. If she creates her own account, is that going to mess anything up with our tickets (we have 3 day park hopper tickets and DAH tickets).
