ADR vs PS?

[mollygirl]

The last time I was at WDW, we needed to make Priority Seating arrangements. Are the ADRs just a new name for the same thing or is there a difference?

They're the same PS is priority seating, like you said. ADR stands for advanced dining reservations. Not sure why they changed the name. The only thing that has changed is the time frames. Before it was 90days, someone correct me if I'm wrong, but now you can make the reservations 180days in advance.
