The following is an excerpt from the Telegraph, which speaks of the speculated fate of the Valley of the Kings and Queens:
Outside of Bangkok, two of the planet's least lonely places are Egypt's Valley of the Kings and Valley of the Queens, where bus-loads of tourists tramp all over the pharaohs' tombs. Sadly, the horde's humid breath raises the moisture level in the closely confined chambers, accelerating their decay. This means that visitor numbers will soon be severely limited – experts and dignitaries only, I imagine – while replica tombs will be built for the gawping masses.
I hate to say "I told you so," but...I told you so! I wouldn't go as far as to say that these replicas will be "no more alluring than Las Vegas" because they will be far more precise and true to Egyptian craftsmanship (one would hope, anyway). Like I said before, just close off the Valleys (I don't care if it takes years...just not too many) until technologically sound protection to all contents within each Valley tomb is implemented (I certainly would not mind looking through Plexiglas). Of course, that's easy for me to say. If worst comes to worst, I'll just load up my credentials with so many degrees in Egyptological subjects that Zahi Hawass will have no choice but to let me into one of those chambers.
