Something doesn't compute with Riku's last comment. A couple gets in for 2,000 yen, so it's 1,000 yen per person. We can't see the student price, but it's 1X00, probably 1,300-1,500, seeing how the general price is 1,800 yen. Regardless, it will be more expensive than the 2,000 yen plus a little kid's ticket for Sora.
