Mostly just mirroring what Dave is saying. There’s a lot of the touristy stuff you can do -fishing, shows, etc or you can go off the beaten path and do some hiking or camping (or both like a buddy and I did).
Or hey, it IS Maui, you could probably spend the entire time on the beach and have an amazing time (well I could but then I -love- the sun, beaches and bikinis!). 😉
Have a great time!
