I have been to Dubai a total of eight times since 1997. My last stay there was in '09, which lasted nearly 8 months.
It is not a place that is easy to navigate by any measure, regardless of the hour. Durex has their job cut out for them. The streets of Sharadiya, for example, are not a place where I would enjoy to be doing deliveries at 2am. Granted, other cities (London, Vegas, Phuket, Barcelona) will have different behavioral mechanics for this sort of business, but that misses the mark altogether.
The main point is this: a shift in paradigm is what's needed regarding sexual health and protection. Seeing condoms as something that people will wait for (for up to 1 hour, no less) before they engage in sex is a catastrophic bag of fail.
The whole point of prevention is —well— being prepared, ahead of time, on the ready.
A monthly condom delivery service like Mexico's http://rubberit.co is something I can see growing on better footing. It's sustainable in that it retains clientele through membership, it is discreet in that it allows the user to place any name as the sender, and it is also socially engaging because for every condom they sell they donate another one to rural and disadvantaged communities.
I mean, good luck to Durex. Their promo is bad ass. But I can see their project folding by mid-year. (Sorry for the long rant.)
