having personally installed more dance floors than I care to remember, even for the purpose you are stating.

I have worked in studios, many times , with " artificial" flooring. This material was NEVER designed for dance use. It is often used for economic reasons , and I can tell you from 1st hand experience, no matter the care, it WILL detereorate eventually.

The investment in wood does 2 things.. both important.. 1.. great surface on which to dance ..2.. add value to the room and the house .

Sprung floors are relatively easy to instal .The choice of hard wood is as much about cost, as it is about longevity . Most woods will outlive all of us if properly treated .Maple and oak would top my list .

Do NOT put polyurethane on the finished floor. A good parafin wax is all that it needs .
Go to a lumber yard for material NOT to a DYI or chain outlet.. you will get a better price for volume .( and advice )
