We were there when the changes took place. I have mixed feelings about the podium being moved. On one hand, it cuts down on the traffic by Kona. On the other hand, it creates a large line just outside where you enter/exit the elevator which got a bit chaotic at times as strollers/wheelchairs were waiting for the elevator.
We went twice to Ohana's, once with a reservation and once without. If you have a reservation, the changes are fantastic as it cuts the line down significantly and you don't have to wait behind people putting their name in.
However, the way they handle the line without reservations is completely ridiculous. Basically, they have you stand in line and as tables become available, someone comes out and says 'who has a party of 4; a table is ready'. The first party in the standby line with a group that size gets the table. They don't take your name down or give you a pager and let you wait in the bar. You stand in the line until a table becomes available and they will give you no indication if/when that will happen. We were the 10th party in line but we got a table before 3 of the other parties ahead of us because a table happened to open up that fit our group size. We probably waited in line an hour. It seems a very silly system and everyone was pretty upset about it but I guess if they are trying to discourage standby parties, it will work.
