Inexpensive laminate flooring can have a wood veneer surface, and be a perfectly acceptable surface to dance on. Mostly, a solid wood floor is protected by a surface coating (wax preferably), and we are dancing on THAT, and while we can see the attractive woodgrain through it, we are not in contact with it, and the spring/give that a good floor comes from the way that the surface is supported (that is, the springing, however it is achieved) and it is nothing to do with the top layer itself.
