There was a vote for the 2016 National between Anaheim and Atlantic City. Many of the dealers voted Atlantic City (which won the vote of course) since the dealers didn't want the west coast site. The reason Atlantic City was even considered in this last vote was because basically the National show promoters will pay next to nothing for the Atlantic City convention center for next years National. The 2003 National was horrible for dealers according to what most of the dealers honestly said. But, they were willing to try it again.
I personally think the Atlantic City show will be a total disaster, for a variety of reasons, many logistical. Most west coast collectors will not attend, so that will eliminate a lot of those collectors. I guess the one good thing is that most New Yorkers and Philly guys who went to the Baltimore shows by car or train, will definately drive or take a train to the Atlantic City show. So, the show will look very similar to the Baltimore National in terms of attendees.
I plan to be there the entire time.
