Driving Down to JB...?

the title ended with a question mark. should i or should i not... very tempted to do that. long journey, i know. but i have never done that before.... it's just tempting. 4 hours on the road... should not be a hard thing to do. wonder if i would fall asleep driving half way... sigh... can't decide. tomorrow better get up early to at least call and confirm if there's still train ticket. then only decide what to do next...sleepy..
