I prefer the overall magical look of the old ones, but I think this one is better because it looks more like a "save the date." The old one looks more like Disney marketing material; it reads more like a "Come Vacation at Disney" brochure, and then your wedding is an afterthought on the last page, whereas with this new one, there's no mistaking it, it says clearly on the front that it's a save the date.
I actually had a couple of guests who thought that the "Save the Date" was the invitation itself that Disney had sent out , and they would tell me or Val, "Oh, I'm sorry I haven't responded yet" and we would tell them, "Oh it's alright, that was just the save the date, we haven't sent out the invites yet." I think that was the case because the save the date was WAY too muddled with info that didn't pertain directly to the wedding.
