Is there a ddr machine at this location?

Yes there is

Sure is

And

I think so

I believe there is, if I'm not wrong

Yes

Its a DDR A machine, connected to e-musement. Need an e-musement card to unlock all the features. You can ask at front desk for one

Yes. I also believe they have something similar called "Pump It Up" which has diagonal arrows instead of the normal ”+” layout like DDR. If not, DDR should be there.
