Every time I crunched the numbers I always concluded the Dining Plan wasn't designed to save money at all like so many happy customers make it out to be. If anything it is just prepaying for your food, at times even prepaying for food you might not want.
So I'll just continuing using my own method of prepaying. I just use my various credit card rewards points to purchase Disney gift cards before a trip and just set our own food budget. The great thing is if we don't use all of it we can just roll it over to the next trip, or use it for some merch, etc. We do the same for Disneyland, so whatever we don't use on one trip will definitely be used toward the next Disney trip, and so on. No need for a Dining Plan for us. But if it makes others happy, I wouldn't want to take that away. I'll just keep using my method.
