I was kind of a 1st timer on our Sept 2007 trip. It was my first time staying on site, first multi day trip to Disney, first time on the Dining Plan and first time visiting the Animal Kingdom. We were two adult women (Grandma and Auntie) with a 5/6yo boy.
Before I forget check the Disney Calendar for the time for Wishes. I think it would typically be 10pm that time of year. So you would make a late dinner reservations if you are trying to watch it from a restaurant. Something like 8:30 or later.
Coral Reef is a don't miss for your girls and the food is wonderful too.
Chef Mickey's at the Contemporary Hotel fun for the whole family and good food at breakfast or dinner. Characters include Mickey, Minnie, Pluto, Goofy and Donald Duck. They will take a family photo before seating you. Unlike the other photos at character meals, this one is an optional purchase. I bought ours with no regrets. As a first trip you too might want this momento. We took our resort bus to MK then walked back to the Contemporary.
Narcoossee's at the Grand Floridian. Fantastic food (steak and lobster too). You can see both Wishes and the Electric water parade from the deck there. We did this on our arrival night; a very nice start for a trip to Disney. We took our resort bus to the Magic Kingdom then took a boat over to the hotel; a very pleasant ride. The boat let's you off right at Narcoossee's. If you have time be sure to roam the hotel. It is the Grand Dame of Disney and worth the time. It is the site of the Gingerbread House during Christmas. Like California Grill it will require you to use 2 Table Service credits. It was our best meal and meal experience of the trip. All of our TS meals were good. Just make sure some one orders the Year of A Million Dreams dessert. It will take your breath away to see and make your eyes roll back in your head when you taste it. I'm am not a big fan of cheese cake and it did those things for me.
Hollywood & Vine Fantasmic package. I think this is a good choice. You'll see a lot of negative comments on this place. It was a good meal, more ordinary than others we had at Disney. But for your family and plain eating DH it should be perfect. It worked for us. The food was fine and Brenda our server was great. We were late for our ADR (more than a few minutes

) and they sat us anyway. We underestimated the travel time from MK to the Studios. They were turning away walk ups while we waited for our seating. So for all the complaints, many, many people eat dinner at H&V. I wouldn't spend 2TS for the Fantasmic seating (so no Brown Derby for us) and the Mama Melrose menu seemed too limiting, though others love it.
Boma at the Animal Kingdom Lodge This is a favorite of many posters on these boards, including my family. We ate dinner there and might try breakfast next time. Though there are lots of different foods there are basics as well. The kids area is full of them (mac & cheese, nuggets, plain veggie) an the full buffet has them too. Breakfast has the basics and made to order omelettes (probably would do over easy, etc. as well). There is a very unique soup bar there too. The breakfast is one of the least expensive Table Service meals so if you're on the dining plan and over spend your credits on too many 2TS meals this would be a good choice of one to pay for off the dining plan. Plan to visit the Lodge while you're there. The girls and hubby will likely enjoy the decor as well as the animal viewing there.
I think your DH will just have to put up with one Princess meal at Disney. He lives with 3 girls so somehow I think he's used to these sacrifices.

We enjoyed
1900 Park Fare years ago for dinner. It now includes the step sisters who I hear are a riot, so DH might also have fun here.
Cinderella's Royal Table is in the castle itself which is probably the most Disney experience you could have. We have not done that one, but it will be a nice treat some day. This is one of those photo included meals and requires 2TS credits as well.
The best advice I received before my trip: You cannot do it all, so don't try!
Pick some places. Make the ADRs and just go and enjoy. Hopefully you'll love it all. If not you'll cross it off the list for next time.
