Alexandria Harbor was basically located in the center of the road between the Port of Mersa Matruh and Cairo. After a similar journey, Zhang Zian and the elfins finally arrived there.
The Port of Mersa Matruh was totally a tourist city. There were only around 15,000 locals living there. In China, this would be considered a small town. Perhaps some bigger villages would have a larger population than this place.
If you wanted to visit the inner parts of Egypt and historic sites, the hot summer would certainly be inconvenient for the journey, but in the Port of Mersa Matruh, summer was the peak season of tourism here. The number of tourists far exceeded the local population, so all the hotels would be full. Fortunately, summer and Ramadan were just beginning, so there weren't so many tourists.
