I just got mine, and I have an idea!! (But know nothing!)
Just today I was replying to an email from a rep I had contacted from a large multi armed travel company (think escorted tours, River cruise line and drum roll please, organizer of independent but organized trips throughout Europe. I think this may be the Disney plan- not just a new destination, but the ability to choose say 2-4 (or 6!) cities, where they do the logistics.
ABD would leverage their partnerships with lodging, and transportation to get you from city to city, house you in their preferred hotel and in each city there might be a representative at the hotel to direct your touring independently, make dinner recommendations etc, but you would tour on your own, possibly at prearranged sites. I really think this will be the next "wave" of travel products, not fully escorted, which aren't needed for the more mobile and well traveled generations coming along, but fully vetted and organized for the overly busy families of today. That's my prediction- I write a travel blog and follow travel news and trends, and that's my prediction! (I'm not so good with sports predictions, I had Kentucky in my braket, so we will see how I do with travel predictions, lol!

)
SayHello- it's an Insiders teaser mailing saying they are announcing April 14, on a special website, "soon you and your family will discover more great destinations than before on a single trip, in ways you'd never expect, with legendary service and magical touches that only ABD can deliver". It also says Insiders can book before the GP. I thought of my theory because it also says "a new WAY to adventure is almost here" and I was coincidentally working with a company that offers that! (Emphasis on WAY is my own)
