I'm bringing my kids to WDW this summer. We have a 2 bedroom villa booked at the Beach Club Villas. My Mom is planning on staying two nights with us, but not going to any of the parks. She will visit the spa, pool, restaurants, and night shows. Do I need to get her registered and get her a magic band? She will likely pay cash for anything that she does while we are at the parks. I know the rooms are based on 2 adults, so I am assuming the price won't change since it will just be her and I and my two kids.
