I just came back from universal. Not sure if this was posted. they now have the security checkpoint before you get to citywalk instead of at the front of each park. I went two days to universal and the first day when we paid at parking we were given a little note that said no outside food, drink or coolers allowed. When I exited the park I asked the security guy and he said you can bring in snacks. When I went a few days later I did not receive the little note.
