Well, I'd say that remembering an assembly/convention from being a kid to a teenager is a lot different than remembering the same conventions as an adult.
One 7 day convention that us kids had a blast at, and I actually remember somewhat fondly (from a kid's summer vacation perspective), my parents still bitch about - the long drive, the expense of a hotel, the 3 sessions a day, the sunburns, the heat. All that was lost on us kids that had a blast playing during the breaks, and sleeping during the sessions, and making new friends.
