Yes. I am really really good at searching for stuff and all mentions of family collection are no longer anywhere they used to be in the Help documents. I think it’s no more. But you’re covered!
It didn’t seem to work anyways. I constantly got inquiries and requests from people who mentioned their children and then I would have to tell them about the Family Trip button, so I don’t think it was very effective. It makes more sense to just funnel people with kid guests into the family friendly listings.
