I got the Copper weekend package. It doesn’t come with any autographs or anything but it’s cheaper than getting preferred seating for each individual day, plus you get complimentary admission into the Saturday Night Special, which you don’t get with preferred seating. I personally think it’s the best option, unless you want to spend extra for the better seat and the complimentary autographs.
(The prices below are based on the Chicago convention, so there’s bound to be some differences, this is just for example.)
If you do the math, the Silver is about the same price as the Copper, but the additional cost (~ $260 more) ends up being the same as you would be paying if you just bought the autographs separately with the Copper package. The Gold ends up being the price of Copper, + $400 in autographs, + about $130 more for the closer seating and the special J2 Gold-exclusive panel.
So, I went with Copper because it was relatively cheap and I wanted to spend the extra money on photo ops rather than autographs. So it really depends on what you want and how much you want to spend.
But yeah, I recommend buying tickets as soon as they go on sale. And you definitely want to get an aisle seat if you can! (Also, this is kind of irrelevant right now, but the Karaoke party doesn’t have seating, so you want to get in line really early if you want to be close to the stage.)
I hope that helped! And I hope to see you there! c:
