Hi
We did an independent trip to Egypt last year from our home in Cyprus and arrived in Aswan going up for midnight. We didn't really want the hassle of fighting over taxi prices at that time of night so I searched around for private transfer prices.
We arranged a mini-bus transfer from the airport to our hotel in Aswan (about 20 to 30 mins by road) and the best price I found was through the Transfer option on HotelClub.com (if I recall, the service is supplied by Octopus). The cost of the mini-bus was a fixed price - a little less than £10Gbp. There were 4 of us! Just checked there now and prices for private transfer from SSH into Sharm resorts is £22.50 for the mini-bus, not per person.
However, I did check a number of other transfer sites such as Resort Hopper and Flightline and they were ridiculously expensive by comparison.
easyJet offer flight transfers to Naama Bay starting at £8.40 pp single journe and £13.20 return on a shuttle transfer of around 40 minutes and £30pp or £56pp for a private taxi (about 10 minutes shorter transfer time). So, it gives you a bit of an idea....
