We'd been going for years when it was at the Cannery in North Las Vegas, but haven't been to this one (recently moved to this casino starting last year) yet. Basically, there are booths (merchandise), lots of food choices (skip the malasadas- they're sad and on the hard crusty side) and two nights of live musical performances (friday is for the younger crowd- jawaiian/hip hop, saturday is for the more mature crowd- more folksy type Hawaiian music). This pacific island celebration takes place twice a year (April/Sept) and is held for 3 days: friday, saturday, and sunday. There is a drawing. There are hula performances as well.
Fox 5 News is a sponsor and they usually have their personalities there too. I saw Rachel and Darren once.
Once we went on saturday morning, and saw O-shen, who performed the previous night- my husband asked to take a picture with him- that was really cool.
