I have spent the past 7 days with my wife and 12 year old daughter in Disneyland and at the beach. My daughter is very healthy, fit, and plays rigorously on an elite basketball team. We walked four miles a day just to get to disneyland at 6:30 each day. We then walked around the park for about 14 hours, then turned around and did it for five days in a row. On the return trip we were eating breakfast at the hotel ans she stood up, placed her face in her plate and either passed out for less than a minute or had a seizure. I think it was extreme exhaustion. This was 3 days ago, and she has not shown any signs of anything being wrong. Should we take her to a doctor, or continue to closely monitor her?
