Cook Islands dancers are renowned and "island night" performances are staged regularly at the hotels and restaurants. A buffet of traditional Cook Island food (umukai) is laid out, and those ordering the meal can watch the show for free; otherwise there's usually a cover charge. Things change, so call the hotels to check. Best of all, try to attend a show related to some special local event when the islanders themselves participate (look in the newspaper for listings).
On Thursday and Friday there's an island night at the Staircase Restaurant and Bar, upstairs in a building beside the Beachcomber Gallery in Avarua. The Edgewater Resort has island nights Tuesday and Saturday at 2030. The Taakoka Troupe often performs at the Edgewater on Tuesday with Orama on Saturday (ask). The island night buffet with dancing is Tuesday and Friday nights at 1900 at the Crown Beach Resort. The Manuia Beach Hotel in Arorangi has an island night on Saturday. The Rarotongan Beach Resort usually has shows Wednesday and Saturday at 2000. The Pacific Resort at Muri has an island night with children dancing on Friday.
