Hello, I lived in Maui for 3 years and visit my family there once a year..not lots of night life anymore but if I were to choose a place to stay it would be Wailea. A nice bar/ irish pub close called Mulligans..it is fun and they have dinner and a show usually on Friday night. Also a few fun bars in a section of Kihei off off South Kihei Rd. The plaza/area they are located in is called the Triangle and is next to Foodland. Lahaina is also nice for night life but it is a pretty far drive from the nice hotels in Ka'anapali. If I was to have a wedding in Maui I would do it at one of 2 places depending on guest size and budget..The Grand Wailea Hotel (best pool and swim up bar on the island) and beautiful chapel or at Mama's beach house. Let me know if I can be of any help to any of you.
