Your welcome Sarah.
It was really easy. Just took my passport along, queued up, handed over my money and that was it. Took about half an hour.
The visa's are rubber stamped into your passport ( not the self adhesive ones like the new entry visa ).
After they stamp the passport they then write period of stay ( which is the expiry date of the residency visa ) and the fee ( 83.10 LE ) and sign and date it. It clearly states Work is not permitted.
The multi entry one is more or less the same and was 61LE ( cheaper than buying from the Consulate in London which is £18 )
Make sure that you make them aware that you want a multi entry one and make sure that where it stated number of visits that they write several.
I took an Egyptian with me and would advise to do the same as they spoke very very little English.
