In Gorgora (p 213), the Gorgora Rock Resort as of July 2013 never got built, and indeed, not on one brick got laid that I could see. However, the lovely Tim and Kim Village is nearby. You can find details on timkimvillage.com. There are lovely chalets on the shore of Take Tanna, and it is 10 minutes walk from Gorgora. Camping facilities are also available. Tim and Kim employ and train local staff and it is (by a long way) the most relaxing and pleasant place to stay in that part of the world.
On my trip I got fly strike by tumbu (or mango) flies. The gravid females lay their eggs on damp cloth and the larvae hatch out and burrow under the host’s skin. As they develop, the maggots cause a massive inflammatory responses and are extremely itchy. I had a total of six! My advice would be that if travellers have insect bites which do not settle down after three days or so, they should seek medical attention. If not treated, eventually the larvae leave the host and the cavity they created should heal up, but they can leave abscesses and it is generally not very nice.
I attended a folk club in Gondar and did not have such a positive experience as you did. There were some extremely drunk locals who I found a bit intimidating (although no-one threatened me), and the musicians and dancers kept on insistently hitting on me for money. I would advise ferengi to go with a local, or at least with a friend.
Otherwise I found the guide to be extremely helpful, so thanks for your efforts.
