I was able to pop in to the show a few times while I was up visiting my kids. A few random impressions:
-- The show itself was great; I still find myself wishing that I had had more time to spend there. Although I was disappointed that I wasn't able to participate more in the auctions due to the relatively high level material being sold most of the time, I did get a relatively modest item in one of the Siegel auctions in a funny way. The auction room was full and I hadn't had time to get a paddle, so I sat outside and bid online through SAN while listening to the auctioneer inside the room call out my bid and award me the item.
-- I found myself almost hyper ventilating trying to take in the exhibits since there were so many of them and the material was unbelievable. I focused on a few of the award winning ones as well as some of the topical exhibits and thoroughly enjoyed the experience. I will say that the lighting left something to be desired, at least to my tired old eyes; I had a lot of difficulty reading the exhibits particularly in the back of the room.
-- I visited with a few dealers, all of whom were welcoming to a relative novice like myself. They all seemed pretty busy at least at the time I was there. However, I didn't venture near some of the higher end folks like Columbian Stamp Co where there was little activity and the folks behind the counter seemed to be vying for the "Best Dressed" award for the show.
-- The clerks at the U.S. Postal Service station were very helpful and kept things moving although most of us were spending a fair amount of time looking over the merchandise available. I happened to be looking for a particular item that apparently had been in high demand, but the clerk and her supervisor spared no effort to search through the piles of material until they finally found one for me.
-- The Court of Honor was simply amazing with the greatest collection of rare items and fascinating material that I will probably ever see in my lifetime.
-- For me the various meetings and seminars that I was able to attend represented the best part of the experience. Even though the ones I attended were quite specialized and in areas that I wasn't much familiar with, I learned a lot in a short time and was very impressed with the passion that the folks in the room displayed concerning the subject at hand. In one session the guy sitting next to me managed to talk me into joining the U.S. Philatelic Classics Society as an additional resource to help me with my continuing education since I collect mainly U.S.
-- Re a point on which revcollector properly reprimanded me a while back when we were having our headbutting on NY vs NJ, the extension of the 7 subway line to the beautiful new Hudson Yards Station made getting to the Javits Center a cinch. Since I was staying in NJ with the kids and driving into the Port Authority, having the subway available made a big difference in getting to the show more easily.
-- Although I tried to go to the show on another day, the traffic at the Lincoln Tunnel was at a standstill for a long time so I literally gave up and decided to run around NJ and NY State on a nostalgia visiting where I was born, where I lived for a while, and finally ending up in White Lake NY visiting the museum on the field where the original Woodstock music festival took place in August of 1969. Nothing to do with stamps, but it made the overall trip more enjoyable.

Overall, the experience has me thinking a bit more about possibly attending the APS show in Portland in August
