Mum: What's this?

Dad: It's a letter. It says, "You've won a free holiday!"

Lily: Amazing! I hope it's to the sea. I can swim and play with sand.

Dad: No! I hope it's a camping holiday. I can sleep in a tent and get lots of fresh air.

Ben: No! I'd like to go to the sea in a ship. I can watch fish and eat nice food.

Mum: Well, I'd like to go to a big city. I can go shopping.
