Very good answers are given above :) there is nothing to add, except that it is bad to walk in Naama in the heat - there is no wind there. Once the devils brought me there in the summer, so at +45 it didn’t seem enough. It’s good to walk along the promenade there in winter, yes! The best winter place in Sharm. As for the rest, I agree with the choice of areas - there is nowhere to walk near Palmyra, alas.
