Yes, mainly interested in doing the more major must see/do things, probably not as much interested in more minor things, and don't really care about dining.
I presume you will have a car?
IMO WDW has some great theme parks and rides and attractions, no doubt. I would suggest MK and Epcot, especially World Showcase. Eat around the World. Walk out through the International Gatweay and experience the Epcot Resorts area. Take a boat ride back and finish World Showcase. Be sure to walk around and explore each "country" - two of my favorite things are the American Adventure and Impressions de France. Oh, and Kringale Bakery. (If you do a Search here you can find many threads on "Favorite things to eat/do at World Showcase - lots of ideas there. And I see another poster mentioned you'll be able to catch Food and Wine - lucky you! Definitely eat at the different booths, it'll be a blast.) Around the time of MK be sure to take a ride on the monorail. Do the whole loop, and consider getting off at one or more of the resorts to walk through and take a look around. These are what we find to be some of the most enjoyable moments of WDW.
If you do have a car, I would strongly encourage you to pick a resort - I'm going to say Animal Kingdom Lodge, go and explore there, have a meal, then sit outside by the fire for a while, maybe check out the animals on the savannah. This will give you a good idea of why WDW is so loved. It's the small things and the beauty/uniqueness of the resorts that are amazing, as well as the big things, but these are often and easily overlooked. Neither my DH or I had ever been to either WDW or DL before our first trip in 2001. Fortunatley our children were only three years old and we had a car, so we were able to drive around to see the different resorts while they slept in their car seats and we were competely blown away; decided we'd have to come back to try different ones, etc. We still never tire of "exploring" and experiencing things we've never seen or done before, as well as tried and true favorites. Everyone develops their own, of course, but I usually tell people the parks at WDW are by no means all there is to see, and missing out on other things would be a shame, especially if you happen to hit the parks when they're busy and you're like, get me out of here, lol. On our trips now we always build in at least two days to just have down time where we might hang around our own resort, or go see another, or shop, etc. (We always have a car for that reason, among others. WDW transportation can get you places, but it's so much easier and quicker with a car. Not to start a debate

just for the benefit of the OP or anyone else reading.)
I think
MVMCP would be fun for the two of you, but I would try to go on an "off night" if possible, i.e. not a Friday or Saturday. You can either enjoy the unique parade of use the time to do rides while most others watch.
I also really like DHS and can live without AK, but everyone's unique on that. Half a day for either will probably work for you, but you will miss out on some things. I would do One Man's Dream in HS, the Walt Disney museum, and watch the movie at the end. And I would add to Itinkso's list Rock n Roller Coaster and The Great Movie Ride, also. (In MK I would add Pirates of the Caribbean, Space and Splash Mountains, The Peoplemover aka Tomorrowland Transportation Authority, and Carousel of Progress if it's open. Oh, and get a Dole Whip in Adventureland (pineapple ice cream or float). In Epcot I'd add Living With The Land, maybe Turtle Talk with Crush and Little Mermaid ride in Living Seas (why not, it's cute and cool when it's hot out). But most time would be in WS. And for AK I'd add Cali River Rapids (you will get wet, tho), It's Tough To Be A Bug and try to catch Devine in Asia.)
You've probably noticed that a little planning goes a long way in WDW. You might want to check the Crowd Calendars just to give you some idea of which park to avoid on which days, etc. It would be awful if you got somewhere and it was super crowded if it could have been avoided. I'm sure there are people who can help you with that. A general rule of thumb is whatever park has Extra Magic Hours (for Disney resort guests) that park gets busy and stays busy for the whole day, so some people employ the strategy of avoiding that park that day. That's completely oversimplifying, but you get my gist. If you're just dabbling in a vistit on this trip, I'd use the avoid strategy and go where it's not going to be super crowded, if possible.
