We have gold card and family was denied admission citing food and beverage policy. There is no reference of any policy section on entire website about food and beverage policy. After inquiry the guest services informed about vague mention in FAQ's but does not describe how people with allergies will be helped. I am a diabetic and my daughter is allergic to almost all meat based products. Further, I have been admitted to the park 5 times this year and never told about this strange policy about parks not allowing customers to bring their own food. The security guard constantly citing reasons as website and there is no mention in any policy of being denying admission for bringing own food.
