Hello!
One thing that saves us $ on food in the parks is grabbing a couple of snacks from home. We are big snackers.....esp. when everyone around us is eating!!
. I bring things from home (fruit snacks, granola bars, skittles) and carry them in my purse..saves me from needing to buy a $4 snack when someone gets a little snacky.....I have brought water with us before too (with the little lemonade single serve packets you get at the grocery store), but that was a lot of trouble since we don't have a car while we are there, so I'm on the fence about that, but the snacks are super easy and def. saved us some money!!!!
Have a wonderful trip!!!
