Wow! I guess you really don't like the dining plans! And, I guess my family "over-eats" and doesn't miss ordering everything in the deluxe entitlements, since we regularly save 25-35% off the out of pocket price. We've done deluxe dining several times and keep every receipt, so the savings is real and absolutely quantifiable.
I cannot get the math to show a consistent 35% discount by using the Dining Plan unless you go out of your way to order the most expensive items, eat at least 2 sit-down meals each day, and/or re-fill your mug regularly.
Can you really eat over $100 of food every day? It's not so easy.
CA Grill (and most Signatures), Average:
Appetizer - $14 + Entree - $40 + Dessert - $12 + Beverage - $4 =
$70
Of course, if you eat at Narcoossee's every night, you could eat $100 in lobster. But beyond that, you need to eat an additional
$30/day to get to $100. This requires an additional Table Service meal. Most proponents of the DxDP suggest they do Character Meals to satisfy the need to spend the additional $30 for breakfast or lunch. Like I said, it requires [2] sit-down meals each day to get you to $100 of spending. Making and managing all those ADR's is not a vacation for some people.
Oh, I know I missed the snacks with a daily $10 value ($5 x 2 snacks). So now I'm back to - you need to eat [2] sit-down meals (and all 3-courses of the most expensive choices) to break even....and then you need to consume [2] snacks each day to get ahead.
So let's look at the math again:
Unless you try very hard and/or enjoy eating at least [2] sit-down meals each day - you pay $100 for what
might be a bit more than $110 worth of value. Of course, you should also factor in gratuity. And think about the cost of both food and gratuity for food you might not have ordered had you not purchased the DxDP.
As to Tables in Wonderland (TiW), I cannot argue with the cost analysis to non-DVC members or AP holders. However, before I'd jump into paying for a DxDP, I would consider the cost of 1 person in my party obtaining an Annual Pass to receive room, dining, and shopping discounts.
