The gas used in party balloons is party gas not helium. Party gas is 70% nitrogen and 30% helium. How high the balloon gets depends on how full the balloon is to start with. The less room for expansion, the sooner it will burst. Those balloons that do not burst, (and most will do so between 300 and 500m) will reach a state of neutral bouyancy at about 500m. The helium will leak out of the balloon through pores in the latex and the balloon will descend. Even after the balloon has burst, a letter attached to it could be carried a fair distance by the wind before it lands.
You have probably seen large buildings where balloons have been released and are sitting against the ceiling.The building owners don't bother getting them down as they will come down of their own accord once the helium has leaked out, usually within 24 hours.

They will not necesarilly pop. In middle school our class wrote letters and placed them in the ballons. All the students released them. We tried to get responces to see where the ballons landed. I remember getting a few that were from the next state over.
