There's music pretty much every night at the Olelo room. I want to say it started around 6 and went until 11. We really enjoyed that a couple of the nights.
Starlight Hui is an awesome stage show that anybody can go to. That was Tuesday and Thursday at 7.
Sunset was around 6. We planned dinner at Ama Ama around that time. It was awesome. They have a band that comes there too for some quiet background music. I don't remember what time they started.
I would recommend going to target they had all the groceries we needed. It's only about 5 minutes east of Aulani.
Enjoy! I wish I could go back!
