Honestly, that would depend on how late you are running, and what our schedule is for that day. If the rooms are not all booked after your appointment time, then you may be allowed to float. You may also choose to shorten your float and take what time you can. If you choose to float anyway after arriving late, you will still need to exit the float at the originally scheduled time to allow for the next floater to begin their float on time. However, if you miss your appointment time, or the rooms are full at the next scheduled time, which would cause an overlap, you would need to reschedule. It is always best to call ahead if you are running behind to find out, before arriving, if rescheduling will be necessary.
