You cant take food in to theme parks?! As far as i know and have experienced, you can take in however much food you want to to theme parks in England. My dad usually ends up having to be the one to lug around the carrier bag of food lol.
Bluebells makes some really good points.
We often have season's passes to the local places and the idea is to save money....not blow it on fast food.
Besides....that stuff is so very unhealthy!
Plus there are families that have other dietary restrictions as well.....like those with diabetic members.......
