I would think your children would enjoy the atmosphere at Narcoosees a little more than Citricos. Narcoosees sits on the water and has lovely views out the windows of the lagoon and the boats. If you time your meal times, you might even catch the electric water parade and/or Wishes fireworks.
Citricos, although it has nice food, doesn't have much of interest in the dining atmosphere. Most of the window views are obstructed by trees/shrubbery.
