Every year the Wilsons go to the beach for a week’s vacation. There are many interesting things to do at the beach.
The children play games on the sand. Sometimes they build sandcastles（沙堡）. There are saltwater swimming pools. The children can swim safely in these pools and the water is always clean.
There is an esplanade (游逛的广场). This is a long road by the beach. There are many cafes and restaurants on the esplanade. There is also an amusement (娱乐) park beside the beach. This is a place with many kinds of rides.
The Wilsons always stay at the same hotel. They usually have the same rooms. These rooms are at the front of the hotel. There is a good view of the ocean from their windows. The children are a little sad when the vacation is over because they don't want to go home.
