Traveling with AP sister

[disney minnie]

we are visiting Disney and my sister has an AP. we would like to get the AP room rate.

I'm arriving first and don't have an AP will this be a problem?

As long as she has your name on the reservation as a guest but the reservation is in her name, it shouldn't matter. The reservation will be linked in her MDE account so they know she has the AP, I've never been asked to show my AP when checking in.
