I'm not going to visit Africa with my family. I rather go somewhere cool.
Why don't you want to go to Africa with your family?
It isn't worth spending time there.
When you go on a family trip, it's not the destination that is important but rather the time spent traveling with your family. You may not personally think that spending time in Africa is worthwhile, your family does. By going with your family to Africa, you are spending quality time with them that they can appreciate.
I want to avoid it at all costs. We should've stayed home.
You might end up liking it more than you think. Going somewhere new can be a very educating and eye opening experience.
