Sailing
I am not sure that sailing around the world with my family would be a good thing because there's no
doctors on board to help you if your sick.
On the other hand you get to experience  new things and learn while your going to different places.

however you might be lost in track at where your at while your sailing in the middle of nowhere.

One good thing about it is your spending more time with your family.

Nevertheless you can't play on the boat.

Another point of view is you enough food to survive.

In conclusion I think that sailing around the world is not a good idea in my opinion.
