Dear Ms Cole,
I read your advertisement for the summer adventure weekend. Can you please give me some futher information?
First of all I'd like to ask about any sailing opportunities. I like sailing, because it is a very good adventure. Also, I want to know  where can I stay for the weekend. How much does the weekend cost? Secondly, your advertisement for this summer adventure weekend is a very good idea to take a ride on a yacht. I'd love to come on the trip with my family.
Thank you very much for your time.
Best regards,
Zavyalova Anna.
