What to do in Wailuku

Hi everyone, my husband and I are planning a trip the end of April/beginning of May. First time visiting for both of us.

Through our resort reservations we got free tickets to the Maui Ocean Center. I’m thinking that would be a good activity for our last day after check out at 11 since we don’t need to return the rental car until 6:05pm and our flight is at 8:05pm. From what I’ve read the aquarium takes around 2-2.5 hours so I’m wondering what else there is to do in the area. So far I’ve got the Nature Intelligence and the Wailuku Public Library as ideas. I’ve seen some posts saying that Wailuku is not the safest place to wander around in the evening. Any tips on what to do and to stay safe?

Thank you and I’m sure I’ll be posting again with more questions!
