If they are Hawaiian they should love it. If it's too humid for the uke they may sound a little off IIRC?
I had one old dry uke that I humidified gradually over time, when I upped it a little more (old Hawaiian koa) the bridge let go, but the luthier said no, it was just "poorly made", but I said well yeah it's an old Kamaka, they didn't make them like old Martins were made, they were tourist trade and casual, but the sound is great. I did remind him it's really humid in HI and the ukes that come from there where they are happy, and then spend 30-80 years drying out here do tend to shrink, crack and separate. My poor little uke is a beauty for being 70-80 years old, I wouldn't look that good if I survive that long. We humans kind of do that too say in Arizona working in the weather for 50-60 years with no sunscreen, lol!
