Rehearsal!!!!

After spending, hours considering dates to rehearse, we are back to the original date. My goodness, what a problem. Lesson learned is that we can not practise into the regular season. I wonder how other groups manage? Or is this the reason few larger groups are formed unless they are bands, orchestras or choirs large enough to deal with the absence of some members. The good thing is that everyone managed to have their say. Even if the solution is not satisfactory all factors were considered before moving back to that date.
How do others handle situations like this?
