Holiday of a lifetime for my parents

Hi,

My parents have always been working hardly but they were never able to get somewhere interesting, all their life was composed of working and caring about me and my sister. I finnaly decided to take them on tour to explore the Eastern Asia, where they always wanted to go . The problem is that I am just a student at high school and I can't afford to pay for it, even if I take some short-time jobs. I know that they're tired and I would like to give them holiday of lifetime, but I can't. I have saved some money, but it's not enough.
