Ha! To me, apart from the trip to Brazil that sounds a bit like a list of things not to do on a sabbatical!

If you really want to refresh I think you need to do nothing for an extended period: go to a library, soak in a painting, play backgammon, drink ouzo outside a cafe for an afternoon, doodle, colour in, wake up to see the sun rise and go waste time with friends and loved ones.

Hmm sounds like a good idea, perhaps I need a sabbatical too!
