We asked the same question of the Camelback a couple of years ago. While they said children were "welcome" at the resort, they encouraged us to stay at one of the other Marriott Scottsdale properties - Mountain Shadows or Cottonwoods. Mountain Shadows did have an excellent children's program, but my children prefer the pools at Cottonwoods, which is now our regular spot in Scottsdale. There is lots for kids in the area in March including FAO Schwarz, McCormick (sp) Railroad Park and many kid-friendly restaurants. Given a few days I could compile a longer list - email if you wish.
