Just an FYI since I have not seen it mentioned here, and since the home page still lists it 11-7, the actual hours for the Harbor appear to be 11-6 for the days when the park closes at 8pm. After work last night, tried to get to the Harbor for 2 hours, and when I got there at 5, they said it was closing at 6.
A sneaky move, yet benefitial (for the company). I don't think any less people come because it closes one hour earlier, and they save some money from running costs and paying employees one hour less. Food and merchandise sales don't take too much of a hit.
are you sure the hours are cut? I'm not trying to prove you wrong or anything, but i know when i was there on sunday, only a few attractions were closing at six, like wahoo, skull island, and hurricane mountain.
