If you're planning on doing laundry in Egypt or Jordan, you pay by the item. One very small load of underwear and a few t-shirts was a lot more expensive than I had expected. Invest in a few quick dry t-shirts that you can wash in the sink and have dry by morning. I'd also think about bringing as much underwear as you have room for. Keep in mind it will be hot, sticky and dusty...you'll probably want to shower more than once a day.
