Are you able to bring bottled water and snacks into the Universal parks? I had heard through a friend that they do not allow people to do this. Is it true???
We bring in snacks to the parks we go to and Universal, Sea World, and Disney have no problems at all. There's no "sneaking" on our part. The bag-checkers will even joke sometimes about, "Wow, it's my lunch break, can I have some?!"

They're great and don't have no problem at all. Paramount's parks, on the other hand, are very strict about bringing any kind of food/drink items being brought in.
