The show is sometimes called "OTSN" in this forum and others or "the Chicago Show" , both refer to the same event held every fall in Schaumburg, IL (Western Chicago area)
2) There are several other hotels nearby. Last year my wife and I stayed at the Residence Inn just up the road and were quite happy. Just a few blocks' walking and I was at the show
3) The biggest part of the show is the room trading that starts as early as Wed, but is definitely Thursday and Friday. The hotel can be a maze so get a map and take a pen and paper to write down ideas, deals, and locations ("oh no! Where was that great deal on those figures?"). Many suppliers and makers have rooms or suites, they are great to visit. It's fun to meet people like the Reuss family, Andy from K&C, Rick from Figarti, etc, etc. I have only been able to attend for a couple years but I like starting on Thursday AM.
4) Watch for announcements, Figarti and K&C have a luncheon and dinner respectively that are fantastic events for anybody with an interest in the making of toy soldiers. Even without a fine meal these would be great events. If Ken Osen is doing any seminars on scenery you WANT to be there!
Personally, I find it helpful to make a want list of the items you really want so you don't forget. You will probably be in sensory overload by the first morning. My tastes are very narrow but I always find lots of "impulse buying" items at the show.
Take lots of money!
There are several nice places to eat within a short distance of the convention hotel.
The convention hotel is located across the road from a very large mall and there is a nice IKEA store to the north so family and/or spouse can go play too.
Relax and have a good time. Lots to see and do, plus there is the Chicago area to enjoy.
If you like museums go south to Wheaton and visit Cantigny Park. A mansion, park and the 1st Division Museum all in one place. Nice US tank collectiuon outside the 1st Division Museum.
