Jiluka VIP Advice

Hi! I was looking for some advice for me and my friend going to our first Visual Kei concert! It will be Jiluka in London on the 9th September! We have secured general admission. However, I am debating getting VIP but my friend isn't (shes there for the ride and vibes lol). How would it work if I got VIP and my friend didn't? Would we be able to find eachother again in the venue again? Some tips would really be appreciated if anyone has been in this situation or experienced Jiluka VIP before! Thank you!! ☆ミ
