Hi Gary - I have been to El Tor and got my 6m multi entry visa and 12 month residency visa which is renewable. It is about an hours drive from Sharm. My taxi driver charged me £15 return and she knows where it is. This helped as she has done this herself efore so knew the ropes.
It is really easy and you just need to take your passport. Make sure that you get your visitors visa when you land in Sharm though otherwise you wont be able to leave Sharm. They check your passport at the check point when you leave Sharm.

Regards

Alison
