Why is This Man Gay?

I've seen this commercial for travel-facilitator Expedia several times and, each time, I am struck not by the fabulosity of their proffered services, but by the mincing, lisping, precious "boss" character.  I have no idea if the target audience is supposed to know that this fellow is Tim Gunn, described by Wikipedia as

. . . an American fashion consultant and television personality. He was on the faculty of Parsons The New School for Design from 1982 to 2007 and was chair of fashion design at the school from August 2000 to March 2007, after which he joined Liz Claiborne as its chief creative officer. He is well-known as on-air mentor to designers on the reality television program Project Runway. Gunn's popularity on Project Runway led to his spin-off show, Bravo's Tim Gunn's Guide to Style, as well as his book A Guide to Quality, Taste and Style.

So he's a C-List "celebrity" who has something to do with girls' clothes and reality TV.  What's the thought, here?  Very smart people designed, scripted and cast this commercial.  Expedia paid a bunch of money, and apparently decided that this is what they wanted to say.  Well, what exactly IS IT that they're trying to say?  That minor reality-TV personalities are good people from whom to get cut-rate travel advice?  That gay guys know how to save a buck?  That caricatures of prancing gay men can really pack-em-in for flights to Oahu?  Are we supposed to laugh (at or with) this performance, as we're clearly supposed to laugh with Bill Shatner's antics on behalf of Priceline.com?

The Marlboro Man sells cigarettes because smoking is supposed to be rough and tough and manly.  Hot girls sell cars because the testosterone-poisoned purchaser fantasizes that he acquires both transportation and companionship for four years of low monthly payments. Christie Brinkley sells perfume because what guy wouldn't want his girl to . . . well, smell like Christie Brinkley?

Flaming queens sell travel because . . . what?

Can anyone imagine Don Draper approving this spot? I didn't think so.
