I took the family two years ago, and had plans to go this year, but haven't seen a real schedule of what is going on so have not bought Expo tickets yet. And yes, I looked and saw that the 3-day tickets are sold out. Oh well!
We didn't know what to expect in 2017, and arrived at around 8:30 AM on Friday and waited in line for over 3.5 hours to get in. It was crazy. And hot. The line snaked around and around and went on forever. I wonder if they will do something different this year. DH and DS (15 at the time) hated the waiting more than anything. Lines, lines, lines. My DD (18 at the time) wanted to wait for book signings and to get into the exclusive stores. We all enjoyed walking around and looking at exhibits, but we could never get into any of the big presentations (Marvel, any big talks) even though we waited in lines for up to 4 hours. We were really shocked at how poorly the line management was. They queued us all up in some underground parking lot to wait for one of the big events, and they filled it up and then half of the people didn't get in. DH and DS refused to go back the next two days, but DD and I went both days, though arrived later and just walked right in. She enjoyed some of the small talks (Walt Disney growing up in Marceline, an author talking about his Oswald book), but that is all we got to see besides what you see walking around the halls.
Anyhow, she expressed some interest in going this year, so I booked the timeshare, but didn't get the tickets. DH and DS definitely will not be going, and I am guessing that we may skip it if I don't see an agenda pretty soon.
