Since you don't have Park Hoppers or ADRs to worry about the only thing that would restrict your park schedule would be FP+. Try and get the ones that you really want (A&E M&G, 7DMT, TSMM, Soarin', etc.) and let those dictate which park on that day. I would shoot for the FP+ that you want early in your trip then the other days you can play by ear. Let the kids decide where they would like to go. With ten park days you shouldn't really have to over plan. Sometimes it's good to go with the flow. Have fun!
