If you are not broke, do go with an **airplane**.
Entrance fees to the faraon graves, Hatshepsut's temple and Karnak temple (which are the MUST EXPERIENCE) in Egypt are between 15-40LE (10Euros is 70LE). Over there get a cab (check in hotel about the price and ask discount, of course).
ps. take with you
1.water (and buy on the stops as it is available for 5LE-1.5 liters)
2.sun block or a good sun factor (20 or more)
3.comfortable shoes (tennis shoes or so-no sandals suggested)
4.a cap for head, or if not do not forget to pour water now and then on your hair-you will be exposed to sun a lor, especially in summer time ;)
6.money for suvenirs-best to buy is in local factories: original papirus (never mind they have the price you can get 30-35%discount)-very good one can be bought for some 70Eur and original alabaster figures (discuss price and buy top 70% of they initial price...if you have time and are in the bargain mood, go for less, of course)-rather large and nicely done one can be bought for 16Eur
ps. In summertime it is VERY HOT-keep this in your mind if you decide to go for this excursion
Take one day trip to Luxor. It is a must while in Egypt. You will be amaized with the monuments of the anciant egiptians ( the «new »kingdom). The Valley of the Kings, the Karnk Temle, the Luxor (small) Temple...It is exosting tour but well worth the trubble. If you haven't been to Luxor before, DON'T MISS IT !!!
For more visit my Luxor page.
Make sure you arrange one trip to see some ancient historic site. Luxor is a good example. Valley of the Kings and Queens is impressive. This is included in a day trip. Downpoint is a 4,5 hour bus trip (one way) but all worth in an air conditioned bus.
