I can provide my personal experiences with hotels and food
It's just me and my hubby ( no kids) and we drive down several times a year from San Fransisco Bay area.
Many of the best places in proximity will be classified as motels due to outdoor corridors but don't let this deter you. We spent years staying farther away and parking and just this last year we got smart and stayed within walking distance - LIFE CHANGER.
I know favorites here are :
Best Western Park Place Inn :
http://parkplaceinnandminisuites.com/ - They book up fast !
Park Vue Inn :

Desert Inn and Suites :

Tropicana Inn and Suites :

Howard Johnson Anaheim :

I myself have not stayed at any of these yet however will be at Howard Johnson this June 30th-July 4th so can report back then. The ones listed get very favorable reviews from regulars here and are all within 5-10 minutes walking distance if not right across the street. It really makes it easy for midday breaks , which we have found actually very helpful however in February if hours are shorter may not be needed but still nice to be close by! While most have some parking fees , it's still less than paying for parking at the Disney structures or lots.
Considering you have an all adult party I would recommend Parkhoppers personally just because it gives you flexibility , however depending on your touring styles One park per day may be better.
My favorite subject...Disney food !
I have so many favorites but will give my "must do's"
Counter Service/ Quick Service
Disneyland
Plaza Inn - - Lunch or dinner for Fried Chicken - me and my husband often split this because the pieces are so generous. I'm from the south and this chicken is amazing.
Gibson Girl Ice Cream Parlor - Awesome sundaes anmd floats on main street , great for parade watching or to relax
Little Red Wagon Corndog Cart - THE BEST CORNDOGS.
Dole Whip Bar - This is by the Tiki Room and a favorite. If you like/love Pineapple definitely get a Dole Whip.
Bengal Barbecue - Great skewers cooked to order - beef , chicken and veggie. Bacon wrapped asparagus too is a favorite.
DCA
Pacific Wharf Cafe - Delicious bread bowls with chowder and soups. Fresh bread from the nearby Boudin Bakery
Clarabelle's hand dipped Ice Cream - Delicious hand dipped ice cream bars with your choice of toppings
Cozy Cones - Theres several different "Cones" in Carsland offering different treats. We love the soft serve here !
