I became a member this summer, and on my Sept solo trip I noticed a purple light at the mickey tapstile entering the park. I was told this was because I was a DVC member. Then when my wife joined me last week, I would get purple (randomly), but she never did. She was getting mad because the CM would say "welcome home" to me, but she didn't get anything. She's listed as co-owner or co-purchaser on our DVC account. Any idea?
