How much time is too much time between the ceremony and reception?  We are thinking of having our wedding at 12 pm and our cocktail hour stars at 4:30.  The majority of our guests are local, but we do have some out-of-towners, of course.  We live in an area where there is plenty to do and plenty of places to see and shop, but nonetheless I need to get invitations ordered and am not sure what amount of time is too much time and may seem rude if we have it too far apart.
