This is why I'm confused. (And I totally understand what the written rules are, I'm not arguing, but something changed, or someone made a mistake in the past.)
My DH and I are both platinum, but my DH only earned platinum status last summer as I've done a few cruises without him. (DVC member and other family cruises where he didn't go). We often travel with two female friend who are both silver. So, even when my husband was gold, we'd split between the two rooms to increase chances at Palo, mixology etc. One friend got the benefit of being roomed with a platinum, one with a gold so everything could be booked sooner. I specifically remember going to Palo (the 4 of us) and I was the only platinum. My meal (and my friend who was named in my room) were comped. She was silver. She tried to explain to the server that it should actually be my husband who was comped, but because she was "in my room" her meal was comped instead. That specific meal, apparently only I should have been comped, but they comped the room. Maybe the Palo server made a mistake, I honestly don't know...
