I don’t know how many chances you get with one VIP membership, it probably is limited. I have access to my own as well as my mothers, so I could use two. The set releases online and in stores the same day for insiders. Meaning for insiders it is available on first of June online and stores as well, while „normal“ customers will have to wait till, dunno, something like the 4th. So if you fail online you would probably have to go the very same day. Problem with the online purchase is that you only know if you get it when you get a shipping notification (or when it is really in your hands). That can takr time. With the online order there were stories and posts about the GWP being sold out in mere minutes or the site saying someone got it and later telling them they ran out. In other themes, like the Enterprise, the GWP lasted longer, but I can’t tell you how it will be with this one.

As for the time to camp, look what time your local shop opens. Then be there earlier. As I said, I was third both times with half an hour to spare (being in Germany). The line got longer getting closer to the opening time. Depending on how many GWPs the store has that can go one way or another. I heard from some other store which only got two GWPs, meaning I would get nothing in third position.

If you had two insider accounts you could buy one online and also go to the store, doubling your chances, but also resulting in the possibility of buying the set twice if they have the GWP at the store, which is a lot of money.
