I used https://ladyegypt.com and found them to be a good value. They have offices in all the major cities and can arrange anything anywhere in Egypt. For example, they’ll send a minibus, driver, and English speaking guide to meet you at the airport upon arrival, show you some sights, and then drop you off at your hotel at 3 pm to check in. They’ll arrange for a riverboat dinner for you. The best part is that with a minibus, driver, and guide, you never have to worry about parking or finding a Careem! Let’s say you want to go the souk; the guide will have the driver drop you off at a very convenient spot, and drive away to idle for an hour or so, while the guide navigates you around the souk. When you’re ready to get picked up, the guide with call the driver, who will bring the minibus right to you, allowing you to jump in and drive off in a cloud of dust. If you plan ahead, they’ll even take you through bandit country (Sinai - special permit required) to see St Catherine’s monastery and the Suez Canal. Totally worth it! Spend the night at St Catherine’s!!!
