New York school trip

Usually I would ask my parents for money, or try to get a job but given the fact that I am very occupied with schoolwork and drama related activites I cannot obtain a job. My parents both have bounce around jobs but my mother makes most of the money, but she is currently hospitalized due to circumstances I can't really say so my father and sister are struggling to stay on our feet. This is an opertunity I would not be able to get again. The 1800 is the needed price to fly there, stay in a hotel with others on the trip, see 2 shows on or off broadway, and fly home.
