Support my school trip to Spain

I'm Delano, and I come from a less-privileged family, and don't have enough money to go on a school trip with my classmates, I do not need all of the money, but this is just the total cost for the travel. It's a 9-day trip to learn more about Spanish culture and heritage. If by some miracle, I end up with excess money I will do 1 of 3 things, pay for my sister's trip to study over the summer, help my family get better off or I'll donate the rest to a charity of your recommendation. That is all, not super urgent, the deadline is early May, but I would appreciate it if you could donate even a little, as it helps.
