Mine turned purple when we were there for over Christmas. I only heard the "welcome home" twice. I assume that was because of noise levels. For some reason, I waited until the last day to ask why, and was told the it was for DVC. My husband's did not do that. I later realized that on the MDE app I was showing as a DVC member, but my husband was not. I did not bother to see if I could add the DVC account number to him.
