My kids are pretty mellow and tend to not have public tantrums!! They wait until they are home and drive DH and I bonkers!
I have 3 kids and while they could last the entire day, why would I do that to them and US!
My oldest is now 15, took a nap on Sunday afternoon because she is doing so much...I am kidding all she did that day while I worked was was dan and Phil in
YouTube! She is the one hat needs the most sleep. Always been like that. So for her a nap is vital otherwise the claws come out. The first time I took her after she was done with naps, she was 4. DH stayed in the room with our son and I took her to the pool for our mid day break and she fell asleep right after we ate dinner at about 6pm in Epcot so after that it was nap time and she didnt fight it!
My son, 13, can go either way. He is can easily stay up til midnigt and be up at 6. He has always been like that. On his 3 Disney trips, e easily napped at age 2, age 4/almost 5 he fought naps and while we were trying to sleep he kept saying "dad (FYI I am mom) dad, dad, when we go back to the park later can we go back on x..". The only time he easily fell asleep that trip was out last park day when he got a Benadryl because he touched milk (allergic) and had hives. When he was 9 when we last went he did sleep at break/nap time.
Youngest, 10, napped with out issues in her 2 trips.
We are the family that I get up at 6, shower, DH gets up while I am in the shower and *reads*-don't judge, I am a nurse and have seen it all plus if he doesn't *read* then, well then he screws up the entire day like he did the first trip he went on with me and we didn't get to a park until 9:30...the horror! Anyways, he is done by the time I am ready to get out of the shower. Slowly 1 by 1 the kids come in brush and get dressed. They eat while DH is getting ready...he takes a while where as I don't. Then he eats while I am finishing packing/loading up the refillable water containers and we are out the door between 7-7:25 for the early entry park.
We leave after we had lunch. Oh and I like to go in August so yes leaving at high noon is a must! We return to our room and nap until about 3:30-4. Then we all shower (not together) and return to the park until closing. Some nights we are lucky to leave Epcot after illuminations and then get to the Poly to watch wishes.
Max park days are 2 n a row. I give everyone the opportunity to sleep in in non park days. Except me, my internal clock can't sleep in so I am up at 6, bathing suit on and laundry gets done and once it's done it is pool time for me!
That is what works for us. I won't do a park on arrival day because we are already tired from the not sleeping excitement of the trip (the only time my kids are up before they need to be and dressed!). I don't want to start my trip off exhausted and never catch up.
If you choose no breaks, definetlay plan 1-2 non park days.
