Here's some stuff on Turkey...
Turkish Astronomy Links
Not much in Egypt, or Dubai, but the others...just google "amateur astronomical observatories in.....". There's heaps of info. Maybe not specifically for tourists but many of the observatories will be open to the public. I don't think you'll find too many sites dedicated to astronomical tourists....it's not that big a market and most of the tourist mobs would be oblivious to them, anyway.
