Got plane tickets for 6th to 10th. And going crazy around.... now!

I'm speedily planning for all the basic stuff again. even looking at my old thread for tips!

Looking back. Last time it took me 4 weeks to plan it! now I have like 4 days.
And at that moment

I was in love with Mikitty, yet bought a Reina set.

Need some help with the concert goods though.
1.【日替会場限定】ソロ2L判生写真(台紙付き) = This item is different for every concert place, right? so I'll still be getting from the same "Tokyo" stack of one of the 27 girls no matter if I went on the 7th or 8th or 9th. or is it a different set of 27 for each day?
2. Am I able to buy more than 1 of those "hidden draw" items like コレクションピンナップポスター and メッセージ入コレクション生写真? (it was much easier when it was just Momusu items...). 1/27th chance isn't that good odds. For example, could I buy "コレクションピンナップポスター x3" to get a higher hit rate?
Thanks for any help!!
I haven't even got a concert ticket yet~
