Sound's like you'll have fun o'plenty.
Speaking from experience, I'd recommend that while in Vegas, take two shorter trips to the PHOF on consecutive days rather than one marathon session (which you'll want to do once you're there) on one day. After a while, you get groggy, stiff and punchy playing all those machines.
Wake up, have a leisurely morning piddling around your area, have lunch then trundle to the PHOF. Leave before you get sore & groggy (or shortly after maybe) to go enjoy the Vegas nightlife. Then repeat for day two.
Also, personally I really like the downtown area (Fremont street) rather than "the strip", but maybe that's just me. Google "Fremont street experience" if you want to get an idea what's there. OF course this would depend on what you want to do while in Vegas and this is just my personal preference. It's further from the PHOF but still only takes 10 minutes to drive there if you don't make a wrong turn or three.
Have fun.
