Riker could use the exercise. He’s getting a might tubby.
I find it a little unrealistic that Luxanna wouldn’t know how a holodeck works and that the bartender is a hologram.
She’s a little out of sorts at this phase.
Nice rationalization. I’m good with that.
And Lwaxana saves the day! 
A nice light hearted episode. But it would have been totally superflous without someone like Majel Barret’s Luxanna Troi to carry it.
Would be James T Kirk Do?
He’d shrug his shoulders, take off his boots, and have sex with Luxanna. And then have sex with Deanna.
And then judo chop the fish assasins and save the conference from destruction.
And then joke with McCoy about women, and set warp factor 7 for “I’m oughta here.”
I agree with your WWJTKD? scenario, except for one slight point:
Kirk would wear her out. Lwaxana would end that phase immediately upon meeting a man who could outpace even her.
Yes! And then Kirk would eat an apple and say “I don’t like to lose.”
And then he’d say:
“It’s not you, it’s me. I only have room in my heart for one lady, and her name is Enterprise.”
Yeah!! Love it.
