FP+ with 3 four olds

[nyybball2]

I am looking to make my FP+ choices for my upcoming trip. I have 4yrd old triplet boys. What is the best way to make my FP+ Do we make them for the kids for all of them and use rider swap or do we have to also have the FP+ or can we do FP+ for 1 kid but have the other 2 with us? THe other dilema is were are going with my sisters so there a total of 15 people 8 being kids and staying in 4 rooms how hard is it to sync that many people so we can get same FP+ times for rides ?
