Hi, Kayla!
You are going to enjoy Disney's Art of Animation. The Big Blue Pool is a great way to relax during your vacation. The thought of lounging around the pool right now sounds pretty good to me!
When booking multiple rooms, each room will have it's own reservation number and details. In your case, the Family Suite will have the Disney Dining Plan, and it sounds like you booked with a Free Dining promotion. All guests who are on the reservation for that room will have those entitlements. You then have a second room that you are booking, a Standard Room. The guests in this room can add the Disney Dining Plan, but will have to pay based on the
special offer or price it is booked at. Maybe this room will be able to take advantage of another offer, such as a room only discount. Without knowing the specifics of your reservation, I cannot tell what offers might be available.
Your best option will be to book this vacation by calling a cast member at (407)934-7639. He/she can give you details of each room and pricing.
Regardless of which rooms are on which plan or promotion, you should book one dining reservation for your entire party. Once at the restaurant, you can decide how to split the check, so each party's dining credits can be used while others may pay out of pocket. Your server will be happy to divide the check however you wish.
One other item to note: The Standard Rooms at Art of Animation are not located in the same buildings as the Family Suites, so your party will not be that close to each other. The Lion King Family Suite buildings will be the closest in proximity to the Little Mermaid Standard Rooms. You can
take a look at this map to see the resort's layout.
Have a great stay at the Art of Animation!
