I am writing because of your notice about holidays in Floreda this summer for the young guys (and girls). You said it is a holiday adventure' which sounds too intresting but I want more details, as quickly as it is possible. The first thing l must to ask is wear exactly Orlando is? Is it far from Florida? Is it nearby Hollywood? You talk for students from abroad - how many other students will it be and which countries they come from? Of course I have to know the bill for all this - how much! I must have these informations? Yes and how will I pay all this? I got lots of songs in English and I really go for everything American so that's why I love to coming to America. It will be my first time.
And pleese: a bit more informations - cos I need to know more.
That's all for now.,
Write soon
Best wishes,
Marcus
