Thank you for your long comment! Makes me really happy to read such a nice reply to my post. To "go with the flow" is exactly how I like to travel! This is how I ended up couchsurfing for the past few days and didn't have wifi to reply to your comment any earlier.. Sorry for that!

Climbing the dunes was certainly very hard, out of the 15 backpackers in our group only me and one other guy made it all the way to the top!
Camels can make some really funny faces, I'm planning to make a compilation post of the most hilarious camel portraits soon :D
