From Jan. 2015:
Worst = Garden Grill, @ least an hour - maybe longer, place was packed with masses of people waiting to be seated - sitting on the floor, leaning against walls, etc.. Once we were seated the table still had food debris (candy sprinkles) from the previous diners on the table. Yuck, not going back anytime soon.
As par usual = Ohana, about 30 minutes this time, better than previous visits (we'd given it a pass for several years due to hour long waits) and there's more seating, so at least you can maybe find a seat while you wait and wait and wait.
Le Cellier = lunch and relatively quick seating v. dinner and typical 30 min. waits in the past.
Boma = first night was around a 30 minute wait, later that week maybe 5 minute wait (both times dinner.)
Better than usual = Coral Reef, waiting for aquarium front seat and were seated around 20 minutes later v. previous waits of 30-45 min.s and no go for aquarium front table.
Prior visits: As outlined above. Mama Melrose runs late, too and there's no place to sit while you wait. We've been lucky w/ most of our signature restaurants and they seem to run at around a 15 minute wait.
Worst wait ever, so bad I'll not go back - Kona. When we went to check in the party of 12 ahead of us was pleading to be seated even though they had no ADRs, they were seated at a couple of tables and then we checked in 10 min.s early for our ADR - no more tables. About an hour and a half later we finally were seated. Miserable wait, no place to sit, frustrating to watch that huge party at 2 tables w/ no ADRs happily munch away while we waited for the ADR we'd gotten up at the crack of dawn to get 6 months before.
