If I had a billion yen, what would I use it for?

1000000000yen...
!!!
If I had a billion yen, I want to go to around the world by floating hotel.
When I went to Yokohama this summer, I saw a big ship like floating hotel, so I want to ride it.
And through the trip, I want to see many of world heritages.
I also want to make a dress like snow white or cinderella.
After that, I want to donate the money.
Money is important, but not everything.
Working also have happiness, without it, our life become more boring.
I do not want to say whitewashing, but I think so.
