Let me get this right... the park is run down and almost abandoned with no guests, yet they are only 100,000 short of reaching 1,000,000 guests in a year?
That's like 2,500 guests a day that they get, that's not fucking bad at all?! Sure it's not Disney levels of attendance but it's enough that the park shouldn't be as abandoned and empty as the manga depicted it... just clean the fucking place and do some advertising and you're set for that 1m goal easily like wtf...
