Are you assuming RotR doesn't have the capacity that every guest buying a 3-4 day ticket get to ride it? I never mentioned hotel stays.Think about that for a second... how many hotel rooms are there on property (include DVC and Disney Springs area).
Now multiply by 2.8.
Now take the THRC of RotR(oh) and subtract the number of tickets from the THRC.
Then Imagineering should have built a better ride.
Edit: I should say higher capacity ride. The actual ride is great.
