I hadn't realised there were flights from Sharm to Hurghada so had a look on Egyptair . It looks Like they only operate on Friday Saturday and Sunday and are at midday so you would probably need to stay overnight in Sharm inbound . Its still another route to consider . You could also consider flying to Luxor airport and tansfer overland which takes about 4 hours. You are suposed to travel in convoy but there are ways and means
. We managed to get a flight to Luxor for £99 last year .
