My view from the jury room at the Palais des Festivals provides concrete - or rather fiberglass - proof of the imperfect correlation between wealth and taste, the wifi signals of incoming boats sporadically interfering with our handheld voting (their networks named after the boats themselves or occasionally "Master Suite").
The typical harbourside scene reveals two 19-year-old Estonian blondes walking the quayside wishing they were on one of the yachts - all the time eyed by an ageing chap on a yacht wishing he were on one of the Estonians.
Sometimes, I am told, the parties manage to arrive at an accommodation.
This scene is replayed daily throughout the summer. And would be playing out whether you were here or not.
That, quite simply, is the first thing to know about the event. That the town, except in an purely venal sense, gives not a damn for your arrival or your departure. In fact the very intrusion of anything to do with commerce or industry or name-badges sits rather unconfortably with the place - as though you had asked Michel Bras to bring a Nobo board into the dining room.
The town can in any case survive so well on oligarchic and Middle Eastern money that it spurns conference business altogether for the two months of the year during which the Russians pay rack rate.
So your first introduction will be to that peculiar French art of managing to patronise you while simultaneously depriving you of your money. And reminds me of the ageing English aristocrat who, at the age of 83, decided to move his entire household (after 20 years on the French Riviera) forty miles down the coast to Italy. "I prefer to be cheated with a smile", he explained.
All of which said, there is no other place in which such an event could be held. For one simple reason - that on the short stretch of seafront called La Croisette - between the Majestic and the Martinez - you will, if you wait long enough, meet everyone you have even known in the industry. That single topological fact is what makes Cannes work.
Actually two reasons: don't forget that, in the Palais, you get to see an assemblage of the world's best advertising, direct, interactive, promotion and media creativity. Something you simply don't get anywhere else.
I'll leave more discussion of work till later. We're still judging it. Except to say that you should go and view as many shortlists in as many categories as you can: to do so simply recalibrates your brain's idea of what quality work really is. Hence I regard the admission fee to the festival as something to be charged to the training budget, not the awards budget. No other event has this immersive effect.
So, what tips do I offer you? There is very little shopping to be found here for anyone with a penis or a brain-cell. The kind of irritating retail ecosystem where you'll find three branches of Gianfranco F***ing Ferre but where buying a plug adapter is impossible.
Happily there is a small place between the Carlton and the Martinez which will sell you a packet of fags and a Daily Mail: a beacon of normality. Bring all your own clothes plus several pairs of shoes - as you'll lose one to poodleshit.
Bring plenty of books, too: even its greatest supporters would not call this a literary town.
Do not give a moment's thought to which hotel you stay in, or pay much of a premium for it, as it makes no difference to the quality of your stay.
The principal value of staying at an expensive hotel is that your hotel appears on the delegates' list. But why not lie, and say you are staying on the 7th floor suite at the Carlton - as telling the truth will only mean you are flashmobbed by jobhunting creatives at 1am in any case? WPP staffers know from long experience to register late, thus not appearing on the delegates' list at all, since Sir Martin Sorrell is rumoured to scan it with a gimlet eye - no doubt clicking one of those counters they use to tot up the passengers on easyJet.
I would, incidentally, travel here on easyJet. This will at least give you a defensive line when your finance director discovers your dry-cleaning bill has hit four figures. You can unashamedly take a helicopter from Nice to Cannes, too: it is cheaper than a sole-use taxi.
Any other tips? I still have no idea what is the appeal of the Gutter Bar. Surely one of the more clear-cut advantages of reaching the pinnacle of the industry is that one no longer needs to drink on the street?
