I have never been but I thought you needed a few days.
I can see where you are coming from with getting out and seeing loads more stuff.
You totally need a few days there. I spent 6 days at the PHOF on my last visit, still don't think I played everything.
You'll probably want at least half a day at the Riviera arcade as well (highlights include the Taxi with
24 bells on the back of it!! haha)
Then there are the ones I have not even been to yet (Highscore Barcade and Flipperspiel Wunderland to name a couple)
Then if you like videogames there are massive arcades at Circus circus, Excalibur, Buffalo Bills and insert coin
And yes you'll probably want to visit a couple of stripper shows, the porn museum, play a round of golf at the Kiss mini-golf course (where I have my name on the wall for being the first person to score a hole in one, backwards through my legs on the 6th hole

) , jump off the Stratosphere, zipline through the canyons, and stuff your face full of food

- so you'll want 2-3 weeks there
