We will be arriving in Cairo on the 27th of December. We do not meet with our group until the next day (or in the evening). Can somebody give us some suggestions on what we should do during our free day. Obviously we would like to avoid seeing the same things we are planned to see with the tour guide on the 28th. I looked into the "backstreet tour" however at $185 per person it sounds a little pricey for us. How safe is it to just walk around?
Also, will it be hot enough to enjoy the Red Sea (swimming)?
