Well, the queuing area wouldn't be going away, just not have that corral making it like an amphitheater focusing everyone to that one side with the waterfall. They could leave the roof if need be, or use fabric sun shades over the area at a taller height. The square footage would still be about the same. Guests could mill about and focus their attention as each Tiki God starts doing its thing. Again, swapping out the waterfall for Tongaroa, since that is the tallest. The others could be up on rock formations around the perimeter so most guests can see them.
However, I know they won't bother doing any of that, but it sure would be better than the original Florida pre-show. Some people would walk out on it thinking that was the Tiki Room Show itself.
