Maui Nō Ka ʻOi! (Maui is the best)
If you haven't spent time on Maui, please do yourself a favor and do so, it really is the best of the islands! In Wailuku there is a shop called Mele Ukulele that you should definitely visit. The employees are great and passionate about the ukulele. They'll most likely be happy to jam with you and tell you where else to go to find the ukulele scene you're seeking.
Maui has it's own vibe and there is so much to do and see! Your daughter would love it. There is a place called "surfing goat dairy" that you should take her to (if she likes animals like most kids do) and get some sweet chocolate treats while you're at it. If you go during the time of year when the whales are there, there are amazing WW tours to take. The banyan tree park in Lahaina often has art in the park type things, and local artist musician jams. There are so many things to do in Maui! If you pick Maui and want to hear more about what to do/see I am always happy to talk about Maui!
I agree. I've lived on Oahu and returned many times on vacation, but for my peace of mind, relaxation, entertainment and recreation, Maui is the best. The Ukulele scene there is accessible and varied. Retail is much more limited than Oahu, but the uke stores in Wailuku (Bounty and Mele) and the Mele shop in Wailea are well stocked and in my experience, staffed with helpful and friendly people.
I met Arlie-Avery Asiu working at Mele in Wailuku. He is an accomplished Ukulele musician, Na Hoku Award nominee, and a most pleasant person to talk story with. Look him up!
Other Uke musicians frequenting Maui venues that I have seen are: Andrew Molina, Anthony Fluke, Taimaine Gardner, Herb Ohta Jr. and the fabulous Rock & Roll ukulele group, Kanekoa. Venues to check out include: Wailea Mall (free concerts and uke lessons), The Slack Key Show in Lahina, Nalu's restaurant in Kihei the Kihei Library and the Maui Arts and cultural center.
If you want play with others in a friendly, relaxed environment, 808Ukejam, plays on Thursday evenings at the Keolahou Congregational Church in North Kihei. You and your daughter can learn and play ukulele and hula with the friendly people there.
We just booked our trip for next February and look forward to enjoying music and beach on the beautiful Island of Maui.
