brandohsaurus saidI don't think you need them every night, but I definitely don't mind a drag queen being the hostess.
The art is in separating the concept from the talent at hand. A funny & glib drag queen hostess can be a riot; unfortunately, few are talented enough to rise to that level and pull it off, though most THINK they are, in their own deluded minds.
It's the same with ordinary stand-up comics: fans will knock down the doors to see the best. But the best are exceptional, why they become stars while hundreds, if not thousands of others do not, driving people right out the door when they take the stage.
So you evaluate your talent, audition them, make them show you what they can do. If witty repartee from the stage is not their strength (though they're all convinced it is), then you get yourself a separate, non-drag MC, preferably a man for contrast. Dress him up a bit (no jeans & T). Keep the queens doing numbers, not talking on stage, which they'll do for hours if you let them, or else all your shows will run way over, annoying the audience and losing you business.
Trust me, I know this business, its strengths and weaknesses. And the queens themselves will be your greatest strength and your greatest weakness. The last thing you EVER want to do is put any of them in charge of the show. Do that, and you'll be rewarded with drama, cat-fights, competition, rivalry, unprofessionalism, and behind-the-scenes headaches you never dreamed possible.
I would recommend our OP visit some established drag shows around the country for ideas, if that hasn't already happened. No need to reinvent the wheel, when others have done this for generations. Find the best, and copy it.
