I have not been able to get a reservation at O'Hana for our last three trips to the world. I have tried several months in advance to book. I have to say, it is a bit discouraging. It seems crazy to me that this gets sooo booked up. Do you think I should give it a try and do a walk up when it first opens. I have a feeling there may be some advance reservations that are not fulfilled do you think this is a waste of time? I REAAALY want to go!!!! Also tried Chef Mickeys as an alternate since it is for a birthday celebration but no luck there either!
