Booking extra days at the Studios shouldn't be necessary. Then your stuck waiting for a boarding group or another attempt in the afternoon. So un-Disney.
How this ever got approved is surprising unless they intend to roll it out to all the parks eventually. Then it makes a bit more sense.
Luckily, every time we've visited WDW or DL, we've got a BG. But this time there's a few more family members going that haven't been on it yet, so I'm preparing for the worse. lol
