Tiki Mugs in Waikiki

Other than Cheeseburger Land in Paradise, and the Hyatt, are there any places which sell Tiki mugs?

Maybe Tikis or La Mariana?

La Mariana has mugs by Gecko. I believe if you contact Gecko you can make arrangements to see his studio as well.

Yes, La Mariana has a TON, some a bit pricey and Gecko sometimes has some that are only available when you visit his studio (by appointment only). Just go to his website http://southseaarts.com/ for his contact info. He's really cool and gracious, so don't hesitate! He's located on the other side of the Island. If you head to La Mariana, make sure you map it out as it's out of the way and pretty easy to miss... HAVE FUN!!!!!!!

Tiki's in Wakiki also has mugs
