The logistics (the setup) for this movie is nearly impossible

How in Heaven's name could these girls have known that Keanu's family was going away for the weekend?

Did they bug just HIS house? Okay, let's go with that. They'd have to listen in on their daily conversations, just hoping that, by chance, he would be left alone for 24-72 hours. And how long would that take before they got to finding out about that weekend? My wife and I have both been gone on business trips, but I don't see how two perfect strangers would know that or find out about it unless they bugged just OUR house and listened to our daily convos.

How did they find their next victim? Do they go to neighborhoods and bug every house and listen to every conversation to see if these men are going to be left alone for 24-72 hours? That would take FOREVER!

Did they do a stake out? Do they do drive-bys to see if a wife and kids are leaving and then just hope that they are going away for days? Are they teachers who question their kids if their parents are going on vacation and if the daddy is being left behind? (That would go over well with the PTA/PTO).

Let's say that I was a crazed psycho hottie and wanted to torture philandering husbands with my friend?

Where ARE these husbands who are going to be left alone for 1-3 days? How do I find them? And just how do I go about bugging the exact house? And not once, but many times, since I have done this before?

And, if they do bug a whole neighborhood to try to find this one philandering guy, how in the he!! do we monitor all of the conversations?

I just couldn't get past this scenario, because it is practically an impossible setup. And, I honestly couldn't think of any realistic way to accomplish this feat.

And then, even if I accept this major suspension of reality, Keanu lets them into his house??!! How dumb is this guy? A normal real husband would say: "Ummm...just stand out there on the porch and I'll call you an Uber. If that is not acceptable, sorry, but I have work to do and I really don't feel comfortable letting two complete strangers in my house. Plus, I have this nosy neighbor across the street who would just LOVE it if I let two hotties into my house while the wife is away. :) :)"

So, yeh, after that, I gave up on this being a logical movie. I watched it (while doing crossword puzzles) just to see how it would turn out. And, I liked the alternative ending better than the original.
