1. Is it a committed all day event? As in, you're there from open to close of the event (930-6p), or is it personal choice to come and go?
As others have mentioned, you are free to come and go. Most people leave to go grab food at some point. At checkin, you will receive a badge on a lanyard that you wear. People at the door will look for that.
2. Benefits/downsides to question 1.
Depending on how long you leave, you will miss trips through the board lines. If that's your thing. The event usually divides people into 2 groups. The people that do the lines, and the people that do the back room. The people in the lines tend to be more casual traders while the people in the back are more hard core. The lines can take 30min-an hour to wait to trade for 2 pins. The hardcore people don't think it's worth it for what is on the boards. My group would always do the boards, and trade with people in line. The boards themselves are hit or miss. If you get a good refresh, then there will be AP pins to find, but they will be park releases, not super low LE releases. And also there is a group of pins that are "board only" but they don't become valuable. Some people will do the boards a few times, first thing in the morning and once right after lunch, and then head to the back. So they get some board pins but still be able to do hard core trading.
3. Is there an itinerary of events?
Yes, that is usually included with registration info. I think in the past they have had it on the back of your event credentials, but I may be confusing that with NFFC/DFC conventions.
4. Just how overwhelming is this potentially going to be? :anxious:
Initially, a lot, but you get into a flow. And here's a hint for people who want to do the lines. Look for the ones with the people in scooters and large bags. They take up more "space" so even though the line looks the same length as a line that is just people standing, there are fewer actual people, so the line moves faster. People taking up a lot of space is a good thing. Another hint, choose the plain ol' pin boards over the spinners (if they have them). They have cut these out for the most part, but sometimes one or two show up. Sometimes, it's a book, sometimes a coffin. They aren't weighted so when you spin, most people always end up on the same thing. Which means after about the 5th person all that will be in there are the stuff people dump, ie scrappers.
5. How expensive/deadly is the total event to your wallet (on average, if you're willing to disclose, or you can PM me)? RSP, lodging, pick ups at the event, etc.
The RSP is the expensive part. Although, sometimes when you see the pins in person you want to add stuff if they are available. The regular park pins haven't been as plentiful as years past. The rest is traditional vacation expenses. So as much or as little as you want to spend. The event gives you $30 in gift cards which pays for lunch for both days, so that's covered too.
6. Favorite thing to do at the events, specifically please! I know it's pintrading hehehe
It's been awhile since I've been able to attend so I don't know how much of these they still do. Sometimes Scoop and other Streetmosphere people are walking around with lanyards. Sometimes, the booths have give-aways. Sometimes pins sometimes other things
