Are you asking about breakfast? If yes then I would base it on the characters you want to meet. But I will add we were disappointed in our O'hana breakfast a couple weeks ago. The food just wasn't good (eggs came out hot, but cool off pretty quickly on the table, bread and waffles seemed almost stale? Ham was dry.) The characters were fine and we went because we were staying at the Poly, but won't return even if staying there. I'd still like to try 1900 one day, but more likely for dinner.
If you choose O'hana, ask for bacon.
