Hi Eldred,
I do not know much about flooring options or their respective prices, but my personal opinion on a laminate floor is that it does not feel good to dance on. I've discussed this with several other dancers (there is a studio nearby that has a laminate floor), and we all agree that it feels strange.
I'm sure there are many people who will not mind or even notice the different feel of the floor, especially if the majority of people at your studio will be brand new dancers. However, if you are trying to attract either competitive dancers or experienced social dancers, you may have a problem. I cannot say that a laminate floor will necessarily be a deal breaker for everyone, or even the majority, but it's something to keep in mind.
Good luck with your new studio. I hope you have great success!
:) Lorena
