Who Has the Floor?

We all know Peter Pan flew to Wendy's window.
But how high did he have to fly?

I've noticed the number of floors varies in each major production on film.

Naturally, we have to check the source.

Barrie keeps it consistent in his play and novel.

Two have the same as Barrie.

But the other three would have you believe otherwise.

Which two counted in all the floors?

Silent Disney Mary Martin Cathy Rigby P.J. Hogan

Select with your cursor for the results:

The nursery is 3 floors up. (Barrie) Not surprisingly, Hogan shows three. But Disney, too, depicts three floors.
As for the others: Silent - 2, Mary Martin - 2, Cathy Rigby - 4
