Mai's place was great! There are so few options for places to stay north of Waimea, and I feel like Mai's was definitely the best option.
You're just around the corner from Tex's Drive-In (beef teriyaki was great) and just up the street from "downtown" Honokaa. I really recommend stopping at Big Island Goods (the owner is super nice and has a bunch of cool items for sale) and the Honokaa Treasure Mall. The Honokaa Country Market is also a great place for lunch.
The composting toilet can be a little strange at first if you aren't used to it, but it's very odorless and quite clean. Don't let it scare you away.
Overall, a great experience!
