It seems, all this particular email is doing is littering up my inbox, and this forum, at least if you're interested in Sharm during Ramadan.
I'm not a muslim but decided to take Marriott up on the bargain offer in Sharm... but all is not as it seems... For the Ramadan offer (code M11) is not actually available in one of the 3 hotels, that is to say Sharm, AT ALL. Admittedly the M11 code does show up on September 7th but it turns out to be a 25 day advance purchase rate!!
So, at least a third the email upon which this thread is based is pointless, because one of the three hotels is not, actually, offering an authentic Ramadan discount, or at least not the one advertised.
Whoops...
