Dear Peter,
Thank you so much for inviting me to take part in the winter camp organizing by your school in the coming winter holiday. Quite interested, I am writing to learn about farther details.
Above all, I wonder that it is convenient for you to inform me for the specific schedule in advance. Besides, this will be my first experience to participate such a activity. Would you be kind enough to offer any suggestions on whose items I specially need to take it with me?
I am really excited and look forward to it. I would appreciate it if you could give me a reply at your earliest convenient.
Yours,
