We have rented cars the last few times so I may not be remembering very well. We just took a taxi to Luxor from the airport. The driver took us through the tunnel, which I'm thinking is okay since it is close to the airport???, then onto the highway and into the back entrance of Luxor. It cost $20.86 without tip for the two of us. That seems a little high. Has it just gone up that much in the last couple of years or did he take us the long way?
