Yikes, why are some people so rude? Trampoline, do you mean the VIP viewing area on the stage? That's not an area for VIP people who paid, that's All-Access for people who are either performing or Guests of performers. That's going to be very unlikely to pop up on this board but I say, Never say never.
Just keep in mind, they might not play that song. Def have a back up plan. And a fake ring is a great idea, just in case!!! There is a website called overstockjeweler.com that has real looking rings. Women wear fake rings so they don't loose their real ones on vacation... CONGRATS!!!!!!
