I took a day-trip down to E3 this year. It's the second time I've done the day-trip. I don't think I'll be doing it again next year. There's just so much travel time for a handful of hours at a convention where the lines are 30+ minutes long. There's definitely no way I'd be able to stand in the Nintendo line. That thing is at least 4+ hours.
What I was able to play this time: Dragonball Fighter Z, Lego Worlds, Yakuza 6... that's it? Yikes.
