We've had a bad experience with this a few visits ago.
Mainly to do with when the VIP bay is set up.
We regularly have either myself or my wife waiting at least an hour before Dreams starts to try and get a "front and centre" spot for our girls (11,7 & 2) to have a great view.
During a visit in 2013, despite being there for at least an hour before show time - behind the white rope already set up - a CM came along to create a bay in the front and centre spot. This moved us back several feet behind whoever was in the VIP bay and meant our girls couldn't really see anything.
This was approx 30 minutes before the shows start time and of course, all other spots along the front were taken up.
It took 10 minutes of talking and mediating between the CM and my very angry wife to resolve the situation.
One lovely CM who had been kidding around with kids sat waiting for the show to start confirmed how long we'd been waiting in that spot and we got to remain at the front.
On subsequent visits, I always make sure a CM confirms that we won't have to move once we've "claimed" a viewing spot
I hope demand for this isn't great - it seems very over the top.
From the price, I would have thought that the only people who'd pay for it either have enough money not to care or they've mis-understood what you get for the money.
As others have said, you can get a perfect view quite easily without paying extra...
