Kayak’s latest head-scratcher of a commercial targets washed-up crooners who can’t charm hotel “vixens” into room deals and perks anymore.

The Negotiator (aka William Shatner), where are you when you are needed?

Apart from yesteryear’s crooning, the Kayak commercial sneaks in its new pitch that there actually is lots of price differentiation in hotel rates these days, as Kayak advises: “You can save 25% or more on the same hotel.”

And, in other developments, Kayak last month launched a site in Brazil and a beta site in Russia. It also has new sites in Portugal and Poland.

We doubt the crooner will play well in those far-flung countries.
