At the risk of being that one voice of dissent, I will say that my DW and I's tradition is as follows, depending on arrival time (we fly from Texas). If we arrive at the hotel by noon then we add an extra park day to our tickets and usually go to Animal Kingdom for a few hours, then head to Raglan Road at DS for dinner. If we arrive after noon we will either rest, or if traveling around the holidays, we'll take buses to the different resorts to see the decorations, and then head to Raglan Road for dinner.
Now, besides the disparity in travel I will say that to date it has just been the two of us, at least for that arrival day, though we have taken extended family trips. March 2020 will be our first time travelling with a little one and she'll only be around 10 months old so we may or may not change our plan. I will say that DW and I are both concerned that RR might be a little loud for a baby that young, but we do love the food there and our tradition is always to get an ornament at the Christmas shop there and have it personalized as a souvenir of our trip. Going early in the trip ensures that it will be delivered to the resort before we check out. We are entertaining other restaurants at DS for the reason I mentioned, but that aspect of the trip is pretty set, though we are flexible if the right opportunity comes along.
I fully concede the point that DS is far less "Disney", but it has become a part of our trips and something that we genuinely look forward to each time we go. I'm not even trying to change your mind as I am sure your girls would enjoy Storybook Dining, as I am sure mine will when she's older, just playing devil's advocate, I guess. Whatever you do, enjoy the trip.
