My instinctive answer is to say fairly low. I recall seeing a number of two-tops and a few four-tops by the window, but I don't recall seeing very many tables for 6. They maybe able to slide a table for 2 and 4 together, but I don't know if that happens very often (I didn't see it when I was there). It's worth noting that very few tables at M. Paul (even by the window) have a view of IllumiNations. Trees and other outdoor features obstruct the view.
