Todd Hi Sheila. Yes, I've spent a few weeks. Absolutely loved it. We travelled from Cairo all the way to Abu Simbel on the Sudanese border.
Money was never a problem and everything is cheap. A falafel sandwich with salad was about 50 cents. Taxis are cheap too. A hot air ballon above the Valley of the Kings was about $75. Probably a bit more now, but cheap nonetheless.
Only real advice I have is to try to be tolerant in the bazaars. At first it will seem like people are being aggressive and your natural instinct may be to snap or avoid them. Our guide told us to just take a breath and go with the flow. Best advice ever. Don't feel pressured and try not to be defensive. Just have fun bargaining and chatting.
Hope you have a blast :)
