The Maui Ocean Center is great! On the smaller side but that’s good with little ones anyway, and they have a big shark tank! Their educational programs are pretty interesting too (for me and older kids probably, not so much for toddlers)
If you’re planning on going though, beware, it’s also way way over priced for tourists (as in, non-annual pass holders), which is really too bad. I enjoy going with my parents, who have an annual pass an get reduced admission for guests.
There were ukulele lessons going on so Kaya jammed with her cousin). “Dance mommy!”
Touch pools for us usually involve Alex and I touching whatever Kaya tells us to, then “we’ll touch it together” then she goes to town on her own.
