Yes, you can certainly attend the event even if you never go to pick up the CDs later on  

You can do a round of handshakes per each CD you reserve. I believe per every CD you'll get a numbered ticket, the number is random and that means how fast you can enter the event viewing area, so the more CDs you get the better chances to get a good number. Each of those tickets you'll later give for the handshake part. 

For the CD reservation form if you have no one's address (JP Only) for a delivery just mark that you'll pick them up. You could even give that to anyone to pick up later (just give them away or arrange for someone to pick them up and send them to you later). 

^This was different, but so good!

So let the measure!

 

I vote this for the new catchphrase of the year!

Well probably the main difference is the goods line. If you're looking to purchase goods you may wanna get there way earlier as the lines could be enormous. Also be careful of the distribution of the goods lines, as there's usually one for concert goods, and some others for regular H!P shop goods, and others. 

Other than that, i can't think of things to worry about. Usually people in Japan are well organized so just follow the instructions on where to enter and you'll be fine.

Thank you gor the updates, I am really getting into them. Is Iketeru Hearts a trainee team?

So basically Iketeru and Junjou are sister groups, both with members who work at Afilia Cafes. 

Under the same label (Stand Up! Records), there's also Erabareshi, Purely Monster and Idol College. You may often see them doing joint events because of this (they share producers, staff, a former Afilia member is now manager of Purely Monster for example). 

In the case of Erabareshi, Tsunku is also there as producer and often writing lyrics for their songs, the member in this case arent' from Afilia cafes but from Akihabara Backstage Pass.
