DH and I always do this for our one night studio stays before we change resorts and rooms. We've been doing the deluxe since it is only the two of us. It is pricey, but Disney loses money on us....or I should say we get more than our money's worth. We usually stay either at BWV or BLT. We will use one TS for a nice sit down lunch in Epcot (Italy) or Yacht & Beach (Captains Grill). I like getting appetizer, entree and dessert. For dinner it's narcoosees, Yachtman's Steak House, California Grill. At Narcoosees, the poached lobster tail and filet is like a $65 entree. I realize we have to pay the tip on top of that, but it is nice to eat like that once in a while. If we want wine, we use our TIW card for that.
We also get two pricey snacks in Epcot during F&G and F&W. Plus the mugs. You will enjoy having them in December because you can get hot chocolate!!
then again, it is only the two of us....so probably would not get the deluxe with kids.
However.....I read about changes they are making to the dining plan regarding being able to get salad or soup instead of dessert on the regular dining plan. I have yet to see an official announcement from Disney yet....it was supposed to start today. So, this could influence your choice too.
