We have a 3 and 6 year old, plan one sit down a day. It does take time which is perfect for us, since we don’t take an afternoon break. When we have tried to go back to nap the kids either fall asleep on the bus and are wound up and cranky at the hotel or refuse to nap at the hotel. Either way it is a waste of time for us to try to do the break. We schedule ADRs early, like 5-5:30, to give them long break. We can then gauge their level of tiredness to see if we go to a park or back to the resort after. I do wish they would change the cancellation policy to 2 hour notice or something for ADRs. That way it would make your schedule more flexible. I understand why they have the policy, just wish it was different.
