Asking information for a course

Dear Madam:
I'm writing to you to obtain information about a summer course. I'm interested in Tennis. I'm 23 years old, and I want to attend the course on weekends because I work, and it's the only time I'm free.
I need to know how I can get to Ferguson Sports School, from Street Forest, Manchester; that is where I live. I want to know what the best route is.
I have several questions about the course that, if you don't mind, perhaps you can answer for me:
1- How much does a one-month course cost?
2- Is it offered in the summer? 
3- How many people are in the class?
4- Do the dorm rooms in the residence halls have en-suite bathrooms?
I would like to thank you in advance and don't hesitate to contact me if you require any information.
Best Regards,
Aro
