There are new exhibitions like Life Through a Royal Lens and Dinosaurs Are Forever. You can also see old collections and take tours.

Families can have new adventures here. There's a mini farm with animals and a treehouse mystery. You can also walk in the beautiful park and gardens.

The fun doesn't stop in summer. The winner will come back for Christmas and see the Cinderella theme and ice rink.

The best part of the prize is a three-night stay in a nice lodge. It's in the palace grounds and has big rooms and kitchens. It's great for families or friends and you can bring your pet.

Near the lodge, there's a nice town called Woodstock and other pretty villages to visit.
