I don’t hear this one much, so I guess it makes sense that it is ranked low on the list. Too much distance between the ceremony and reception site can be an issue, but I think most couples take this into consideration when planning. The last thing anyone wants to do is spend more time in the car traveling for the reception. It might be a factor for the couple, but for guests, especially those with kids this can be a real bummer. Try to select venues that are close if possible, especially for those who will spend a lengthy time getting to the ceremony.
