I think you need the right balance. The first scene after the drop needs to be big and open to set the scale of the ride. But small secluded scenes are important too. My main critsem of the old ride was that it felt very cluttered. While I love how Europa just keep adding stuff to their attractions there comes a point where less is more. So splitting up scenes sounds like a good idea as long as it's not all small scenes. Pirates at Disneyland Paris does a great job of making scenes feel massive but also separated. However that ride is massive and multileveled so you can have scenes looking down on other scenes.
