I was there last March. The weather was great. There was 5 of us myself, wife and 3 kids (ages 5,7,10) We did all 4 parks in 5 days. Yes the days were long 10 hour days minimum. And YES we were all tired at the end of the day. My brother lives 25 min from Disney so we stayed with him. I carried a back pack with food, drinks and snacks for all of us. Use the "e-pass" as much as you can it is well worth it.
