I have used the little packets that flavor a bottle.
The kids don't like water much, so that helps.
We did a zoo/amusement park 2 day trip a couple years ago.
Both places left us bring stuff in, and the youngest was in a big stroller
with room for a soft cooler.
In two day we went through 2 cases of water and a couple boxes of flavoring.
$5/case x2 + $5 in flavoring=$12
$2.50 a drink at the concessions x the 48 bottles we drank.
I REALLY liked it after that trip.
