We have three days in Luxor later this week, and as we know the town quite well already, we'd be interested in skipping over to the Red Sea for a day before we head off to Aswan - our REAL destination. Is there a convoy system to eg Marsa Alam? Do taxis go ? Is it feasible (and worth it ) to do a day trip. I imagine the scenery is pretty wonderful ... Any tips/advice would be very welcome!
