There's always a chance that the meeting ends early, and I can still get out in time, but just in case, the one-way fare the next day makes sense.
Are there any problems associated with doing this that I should be aware of?
As long as the flight you're missing is the last flight in the reservation, no problem (it sounds like this is probably the case but your wording is a little unclear). If you have any other fights after it, keep in mind they'll all be canceled when you miss the flight you're planning to miss.
