This nostalgia is one of the reasons why the Adrère Amellal Oasis has my name written all over it! I first heard about this oasis over at From the Right Bank to the Left Coast and my jaw literally fell to the ground. It's such a relief from all the massive hotels that seem to be splattered across the country.
The oasis is at the foot of a huge white mountain and made entirely of local resources (let's just say a rainstorm would be the end of this place). All the food is as local as it gets coming from this small town and also grown on the oasis grounds. The rooms are simple and as there is no electricity, they are lit by tons and tons of beeswax candles.
Besides taking along a few good books to read, you can also go hiking up along the mountain, take in the desert views, go swimming in the saltwater pool and explore the local cafes. The hotel has about 40 rooms so it's very intimate and you can always chat up guests like Prince Charles if you get bored.
While there is absolutely nothing to suggest that the 8-hour journey from Cairo would be anything but brutal (books-on-iPod and a whole lot of battery power), I think it would be totally worth it to spend a few days in a place like this.
