When we visited Six Flags in Washington DC area, they did not allow us to bring in our own water and sandwiches inside the park.
We are planning to go to Orlando in November. What I need to to know if I buy water, etc. from a supermarket, can I take them inside Walt Disney World Parks, Sea World, Universal Studios. And if we can't, for example how much do you pay for a bottle of water or Coke inside the parks? And if we don't go for the dining plan, would it be very expensive to have some lunch inside the parks?? Since I am not from USA, I don't know much about these staff. Thank you for your time reading my questions.
