I teach, and we always take a field trip to the zoo. Each child is responsible brings his or her own lunch, drinks,etc. My first year teaching, I allowed money for the gift shop. BIG MISTAKE! Some brought $20, some brought none. I felt so terrible for the ones that couldn't shop. I bought pencils for everyone, but I learned my lesson. Now we just skip the gift shop. Just my two cents.


It is the parents' responsibility to pack adequate drinks for their children, and that means more than one juice box if the trip is outdoors for an extended period of time. And what kind of a place doesn't have any water fountains? My guess is that there were some. Almost everyplace has water fountains outside the restrooms.
only one problem there... the lunches were waiting in the cars in the parking lot and even if the child had extra drinks they were out of our reach.
