You are more than welcome to bring your own food into the Resort. As LEGOLAND Windsor Resort is predominately an outdoor attraction, there are limited covered areas outside to eat lunch. Whether you can bring outside food into one of our restaurants to eat during wet weather would be down to the discretion of the duty manager for the specific restaurant.
If you wish to bring in a picnic/cool box, we would advise you to leave the cool box in the car and then obtain a hand stamp when you exit to allow you to collect it at lunch and return to the Resort. This is because the lockers are too small for a cool box and Guest Services are unable to store food.
