Rv site. Daughter, 8. First time to Disney for all of us. Daily planning would be a great start.
IMO, I would take the day you arrive to get settled, poke around The Fort, maybe spend the evening at Downtown Disney.
Your first whole day I HIGHLY recommend getting an early launch to Magic Kingdom to be there for Rope Drop because that is where it all started. The opening ceremony brings a tear to my eye every time I see it. Enter the park through the left gate and stop at the City Hall to get your "1st Visit" badges. Think of Magic Kingdom as shaped like a lollipop. I start up Main Street on the right side, take pictures in front of Cinderella Castle, turn right to Tomorrowland (Buzz Lightyear, Monster's Inc Laugh Floor, Space Mountain for starters). Head back to Mickey's Toontown Fair and Fantasyland, Liberty Square (that's where Haunted Mansion is), Frontierland, Adventureland, then back to Main Street to explore the side you didn't see in the morning.
Make sure you pick up a park map and time schedule when you arrive at each park and keep them handy. I recommend having a general idea of a touring pattern; but, stay flexible because of parade/show times, fast passes, etc.
There are lots of casual dining restaurants. Unless you are really set on one of the table service restaurants, I would explore and stop to eat when hungry. I don't like to make too many reservations because it locks me into being at a certain place and a certain time. I like to be flexible.
Other park musts:
Animal Kingdom: Festival of the Lion King (bestest show at WDW), Kilimajaro Safari, It's a Bugs Life
Epcot: Soarin', Turtle Talk with Crush, Test Track
Hollywood Studios: Toy Story Mania, Walt Disney: One Man's Dream, Osborne Lights (Sci Fi Drive in is one restaurant I might make reservations for)
Make sure you schedule time to enjoy what The Fort has to offer; especially, fire works and the electric boat parade from the beach, looping to see all the Christmas decorations, and Chip & Dales campfire/movie.
Have a great time.
