Swimming....calories burned?

So today I was babysitting and spent about two hours in the pool. I wasn't like swimming laps, but I wasn't just lounging on a raft either. I was playing with two 8 year old boys tossing balls, dunking them, swimming races, making a whirlpool and being pretty active. The only thing I could find in the calorie thing was "swimming leisurely" and it said I burned like 700 something calories, which seems quite high to me. What do you think would be a proper estimate? I basically cut that and said I burned like 500, but even that seems high. Idk I don't really know too much haha
