My teenage daughter is going to BALI for schoolies.?

I am very worried as they are warning Australian not to go, as there is a possibility of further terrorist attacks, she is sharing a room with friends and the problem is, if she backs out her friends pay more, so she feels she should go, and not let her friends down, what a terrible situation, is anyone else experiencing the same problem, and I hope if she does decide not to go will she get her money back?
