By "two dining packages" do you mean each of you will get a dining package? I hope so, because that is the rule. Everyone in the room MUST be on the same package, so yes, you would have two dining packages because there are two of you.
The regular
DDP is only two meals per night, one counter/quick service (QS) where you go up to the counter, order your food, and find a seat, and table service (TS) where you're shown to a table and order from a menu with a waiter. You also get one snack per night. Do you not normally eat 3 meals a day? How is it too much food? What do you typically eat for a meal when you're on vacation?
For my family, the dining plans do not work because we don't care for desserts and we prefer to drink water. So two entitlements (dessert and drink) are too much food for us. Even on vacation where we might splurge a little more, it's too much food for us, so we look for other discounts. However, if free dining is the best or only discount, then we don't worry about it and we get bottled waters or drink more coffee/tea than we really want, and my youngest (who LOVES sweets) gets to eat more dessert than even he can handle.
Free dining is up in the air for this year. The most common assumption is that there will be some kind of free dining for some dates from Sept-Dec, but it is expected to be fewer dates and fewer rooms available for it. You'll just have to keep a watch like everyone else to see what they do. The announcement for fall discounts usually comes in April or May.
