But are they going in front of the LL folks? If not, why would anyone consider it?
No, they are not. They have to join the LL at the end, wherever the end happens to be. We had a VIP group in front of us recently at RSR in a LL line that ended up being 30 minutes long. The guide SPECIFICALLY SAID "we used to be able to bring guests in through the exits, but we can't do that anymore."
I honestly don't know why anyone would pay for it. It's always been a ripoff in MY opinion, but now it's even more so.
