DO THIS!

Incredible. I've been to 40 countries and 6 continents and had countless adventure - I think this may be the most amazing thing I've ever done. If you're on the fence, go for it! Sell blood if you have to, you will not be sorry. Unless you don't do it, then you will realize in the twilight of your years something is missing from your life. Something you can't quite put your finger on - but I'm warning you now - it would be this trip. Give yourself a hand and go. Spectacular views - and I was in the middle seat. Window would have been nice, but it's great from the middle too.
