It definitely varies by kid/family. When we went in March it was really hot in the middle of the day so we left the parks and went to the pool at our resort. Our kids haven't napped in a long time so we didn't even bother trying that. We ate lunch and then went to the pool. A couple of the days, DD ended up taking a power nap on the lounge chair but even without the naps they were ready to go back to the parks for dinner and into the evening.
