PA28s will float until you get them down to the right speed! It's all a matter of practice (repeat ad lib) until you know the right power settings, speeds, etc. If you approach fast, you WILL float for a long time.
Get the speed right for the version you're flying, and you can grease it on, nose high, with no bother, at the place on the runway YOU choose. My instructor would tell me which runway stripe to land on - and expect me to do that, every time. In the end, I learned to do that.
If it balloons, and until you're comfortable with the aircraft, go around and sort it out next time. The alternative could prove expensive.
