Humm., I've never tried Costco churros.
I live in Northern Cali.., and it snows here.., and it doesn't feel very "Southwest" here.
It depends on what you call a "snack." I can't take eating the high sugar treats all day.., it makes me feel cranky and tired.., and we CANT have that at
disneyland.
That being said, I do love the Dole fresh pineapple and whips.., The Bengal BBQ has excellent cabobs, veggie or meat.., and the Critter place, and a few other places, they have a PB&J sandwich from the child's menu, it comes with grapes or fries (some places apple slices too) and a milk or other kids drink.., it's a great light meal or snack.., sometimes a PB&J just hits the spot.
