One possible version:
Hello, everyone. We are going to have a picnic at Xiangshan Park this Sunday. We’ll meet at the gate of the park at 8:30 am. Then we’ll begin to climb the mountain at about 9:00. If everything goes smoothly, we can reach the top of the mountain at 11:00 am. We plan to have our lunch there at 11:30 am and after lunch we’ll be free. We will return at around 4:30 pm.
Everyone should bring your lunch. Of course, don’t forget to bring some money.
That's all. Thanks.
