We agree with you!! I think some people just don't respond because they have to face the fact that they most likely 'can't go' for whatever reason, not because they don't want to! But, we believe that the people who will end up going, take care of business right away and we don't want to beg anyone to go, that's not the point! If you have to call people to see if they're coming, then those are the same people that hold the cost of the trip and the fact that you wanted them to go, over your head for years to come. We want to spend our time with those who made the effort to be there- willingly!!!
